Tracé automatique du diagramme de Bode / Automatic plan of the diagram of Bode

Bonjour je dois réaliser un programme permettant d'obtenir automatiquement le tracé d'un diagramme de Bode et d'extraire les caracteristique d'un filtre passe-bas. On doit pouvoir modifier le programme afin qu'il permette d'étudier les filtres passe-haut et passe-bande 1er et 2e ordre, le type de filtre sera choisi par l'utilisateur. Voici ci joint mon début de programme qui permet de faire un balayage en fréquence
Merci de vôtre aide.
Hello, I have to realize a program which allow us to automatically obtain the Bode graph and extract the characteristic of a low-pass filter.
We can modify this program to examine high-pass filter and bandpass filter 1st and 2nd order, the type of filter will be choose by the user.
Here is my beginning of my program which allow us to make a sweeping frequency.
Thanks for your help
Sorry for my mistake in english

Hi,
Thanks to post on NI Forums.
If you want to post in French you can ask the French community here
Now, I think I would need more informations on your setup to help you a little bit. First lets recap what you're doing:
You want to characterise analog filters (2nd, 3rd order) and you have some hardware to do so, generators and digitizers.
-What are the hardware references ?
-What is your LabVIEW Version ?
Looking at your program, it appears that you do not have any synchronization between the two loops (generation and acquisition ones) and I think you might need it if you want to know the freqency response of the filter at a known frequency.
So, what you should do is the following:
1-Generate a known tone/frequency
2-Do the acquisition of the signal coming out from the filter
3-Handshake or notifiy the generation loop that the acquisition took place succesfuly
then re-iterate those steps to sweep over the frequency range.
The handshaking can be done using Notifiers in LabVIEW, to know how to use it you can walk through the Exemples
In LabVIEW : Help>>Exemple Finder then search for Notifiers.
Concerning the bode graph, you can use some Maths functions to 20log the signal and then plot it in a graph.
You can also modify the graph properties (right clic>>properties) to edit X/Y scales etc.
Hope that helps.

  • Automatic Plan Order Creation on Sales Order save

    Hi friends,
    We are having an requirement where Automatic Plan Order should be created on Sales Order saving.
    We have Material A in Plant 1000 & Plant 5000.
    Plant 5000 in plant where Manufacturing is carried out & Plant 1000 is service Plant.
    We are using Special Procurement key for Material A in 1000 Plant which triggers procurement from Plant 5000.
    When Sales Order is entered in Service Plant 1000, after saving Order Plan Order should be created in both Service Plant 1000 & Manufacturing Plant 5000 along with Sales order reference.
    I have tried using Strategy Type 81 but Plan Order is created while saving Order only in Service plant (1000), but with Procurement Type (E - In-house Production) & No Plan Order created in Plant 5000.
    Can you please guide me how to meet requirement?
    Thanks in advance.

    Hi Jiaul,
    Thanx for reply.
    I have already assigned the Special Procurement Key to Material A in Plant 1000.
    In Plant 1000 procurement type is F (External procurement)
    But when Plan Order is created after saving Sales Order it is created with Procurement type E (In house production).
    If I delete Firm Plan Order generated & run MRP for Sales Order / Item. It gives me required output generating Plan Order in both Plants.

  • Automatic Planned order creation-Strategy 50

    Hi all,
    I am using strategy 50 and first two levels of the finished material are make to order. Whenever i create sales order a planned order is automatically created for the finished material but for the material one level below no planned order is create, although this material is also make-to-order (ind/Col indicator is empty). Please guide me how can i achieve automatic planned order creation for the materials which are one level below the finished material (Note: Assembly is also of make-to-order strategy)
    Best Regards,
    Shah

    HI ,
    You are using planning stg as 50 " Planning without final assembly ", and this stg you need assgin only TOP level code i.e salable code , and down level codes no need to maintain .
    Once you enter sales order in TOP level code system will generate planned order  and from next level onwards you need to run MRP manually / Scheduled  ( single level / multilevel).
    System will not generate MRP for two level automatically i.e TOP level and next level when you enter SO.
    I hope this will clear to you
    Thanks

  • Automatic plan enrollment error solution required

    I am facing an error in enrollment in SAP HR Benefits module. The config is as below
    --Unimed plan is to be made mandatory. For this, I have configured the plan as "automatic" plan
    --Maintained IT 171 for the employee.
    --The automatic plan option appears in enrollment. But when I am trying to view the automatic plan for an employee, I am getting the error as "Calculated prcoessing end date is before the start date".
    --This error is coming for all the employees
    --The F1 for the error message states: HRBEN00FMODULES218
    Kindly reply at the earliest.
    Thank you very much

    Hello,
    This seems your start date and end date are not matching.
    meaning your end date is prior to start date. it should be bigger than the start date.
    try out this.

  • I have an Ipod1 with 3G and an unlimited ATT plan.  I want to get an Ipad2 - can I swap SIM cards so that my unlimited service will automatically transfer to the new unit?

    I have an Ipod1 with 3G and an unlimited ATT plan.  I want to get an Ipad2 - can I swap SIM cards so that my unlimited service will automatically transfer to the new unit?

    You don't actually swap the SIM card. For some reason, AT&T doesn't like you to do it that way.
    Go to:
    www.att.com/ipadlanding
    edit payment information link...then update the following two fields:
    IMEI:
    ICCID:
    You get this info from the iPad (1 or 2) select 'Settings' then 'General' then 'About'...
    The IMEI and ICCID info is on that screen. No need to swap the SIM cards. This process outlined above transfers service instantly and does NOT change the plan type, billing, user info, or days remaining. Basically anytime an ATT customer wants to move a data plan the ATT iPad web page is all you need. No phone call!
    It took me about 3 minutes and worked perfectly.

  • Automatic plan figures updates at Profit Centre level.

    Hi,
    I would like to know whether do we have any scenario like Automatic Plan figures updates at Profit Centre Accounting level when we do Cost Centre planning.  The Profit Centre should be picked up by the system automatically from the Cost Centre master. 
    Of course, here the Cost Centre to Profit Centre relationship is 1:1. 
    If anybody come across the above required scenario, please let me know how to achieve it.
    Thanks for your inputs well in advance.
    Note: I know we can copy the Cost Centre plan figures to Profit Centre level by using copy function.
    Regards.

    Hi
    In version maintenance, you need to tick integrated planning....
    In PCA, create the doc types for planning and maintain no ranges...
    Also, if you are on New GL and you want to use New GL planning, you need to do settings in new GL menu for the same... assign version to ledger, fiscal year , etc
    last month there were couple of threads on it .. Refer this link for new GL planning settings

  • Starting SQL-Trace Automatically - Transaction Code: ST05

    Good Morning Experts!
    I have got a problem with my "SAP - Business Warehouse (BW) System".
    We have very much Traffic on this System every night (between 03:00 and 04:00 a.m.).
    Because nobody is at work so early in the morning, I wanted to ask you, if there is a possibility to start the SQL-Trace (which you can call by transaction code: ST05) automatically.....?
    Is there a possibility to write a short ABAP Code to start the SQL-Trace automatically?
    Thank's and best regards.

    Hello Rob.
    Thank you for replying.
    I tried to create a job with the "Job Wizard" with SM36.
    Now i realized, that i have to wirte my own ABAP-Report (Programme), which uses the ST05 SQL-Trace function.
    I am not an ABAP-Professional, so would you be so kind and give me the code-lines of this programme?
    I can not imagine if you have to write only 5-10 lines or if the code is much longer...
    Thank you and best regards.

  • Automatic valuation of the MIC

    I want to do the automatic valuation of the MIC (as accepted or rejected) depending on the results recorded.How is it possible?

    Hi,
    Maintain following  -
    1) For the sampling procedure, maintain the valuation type which does not include manual valuation.
    2) In the inspection plan, maintain the control indicator as sampling procedure required & assign this sampling scheme to the inspection plan.
    3) If the inspection characteristics is quantitative, then maintain the target value, upper limit & lower limit.
    4) If the inspection characteristics is qualitative, maintain the catalgue & code groups & codes for the inspection plan. (Maintain the acceptable & rejected codes in Selected Sets before this).
    5) Based on the above settings, system will accept or reject the characteristics based on the recorded results or selected code in the inspection lot.

  • Automate to run the report & save it a name with date prefix

    We are planning to build a new in-house system. And would like to
    schedule some reports running in mid-night & automatically distribute to the
    users. Also, we would like to make a hardcopy per each day in case the users
    need some previous info which may not be found in the database since the data
    might be changed. So I thought the file name of each hardcopy should use the
    date as prefix.
    Do we need Oracle application server for such requirement?

    Hello,
    We have integrated oracle reports into oracle portal and it works great. The reports can be scheduled by a user in the front-end. What I would suggest is at the same time of scheduled report to the user's email is to schedule the same report to a printer. If you have more than one report engine, then your reports will run simultaneously.
    Yes, I think you need the oracle 9ias because oracle reports does not come standalone.

  • Stop Iphone 2.0 from automatically conecting to the internet

    Hello,
    Yesterday I up-dated my classic Iphone 1.1.4 to the new OS 2.0.2. It has worked really fine, but I discovered that it automatically connects to the internet via gprs increasing charges on my phone bill. I´ve changed some settings like:
    *settings> fetch new data > push off > fetch manually*
    *settings> general > network > data roaming off*
    Though my Iphone isn't automatically updating data it is still able to conect to the internet if I press any of the web applications.
    How can I disable this?

    Hmmm.. I can think of anything that will shut off the connection to the web. It will likely be maybe a wireless carrier issue? If you have no data plan the wireless carrier may still feed you data per GPRS. In phones like the Blackberry it lets you know this to either accept it or not per charges. I dont see any option like that on the iphone.

    Bonjour,
    Excusez moi mais j'ai un peu de mal à comprendre votre problème.
    J'ai essayé de faire un test que je vous envoie en pièce jointe.
    Ici j'ai initialisé mon tableau et chaque itération de boucle se fait au bout de 1 sec.
    Etant donné que la seule donnée logique de mon tableau initialisé se trouve à la ligne n ou je met n (attention le tableau commence à l'indice 0) alors je sortirai de la boucle ou bout de n+1 sec.
    J'espère que ce VI répondra à votre question, sinon, n'hésitez pas à revenir vers nous et à nous donner plus d'informations.

  • I purchased my iMac used.  When I try to update my apps the computer automatically fills in the previous owner's Apple ID and I can't change it.  Any ideas?

    I purchased my iMac used.  When I try to update apps in AppStore, the computer automatically fills in the previous owner's email address and it won't let me delete it to enter mine.  I have been using my own apple ID and password on this computer for other things without a problem.  Any ideas?

    Before buying a second-hand computer, you should have run Apple Diagnostics or the Apple Hardware Test, whichever is applicable.
    The first thing to do after buying the computer is to erase the internal drive and install a clean copy of OS X. You—not the original owner—must do that. Changes made by Apple over the years have made this seemingly straightforward task very complex.
    How you go about it depends on the model, and on whether you already own another Mac. If you're not sure of the model, enter the serial number on this page. Then find the model on this page to see what OS version was originally installed.
    It's unsafe, and may be unlawful, to use a computer with software installed by a previous owner.
    1. If you don't own another Mac
    a. If the machine shipped with OS X 10.4 or 10.5, you need a boxed and shrink-wrapped retail Snow Leopard (OS X 10.6) installation disc from the Apple Store or a reputable reseller—not from eBay or anything of the kind. If the machine is very old and has less than 1 GB of memory, you'll need to add more in order to install 10.6. Preferably, install as much memory as it can take, according to the technical specifications.
    b. If the machine shipped with OS X 10.6, you need the installation media that came with it: gray installation discs, or a USB flash drive for a MacBook Air. You should have received the media from the original owner, but if you didn't, order replacements from Apple. A retail disc, or the gray discs from another model, will not work.
    To start up from an optical disc or a flash drive, insert it, then restart the computer and hold down the C key at the startup chime. Release the key when you see the gray Apple logo on the screen.
    c. If the machine shipped with OS X 10.7 or later, you don't need media. It should start up in Internet Recovery mode when you hold down the key combination option-command-R at the startup chime. Release the keys when you see a spinning globe.
    d. Some 2010-2011 models shipped with OS X 10.6 and received a firmware update after 10.7 was released, enabling them to use Internet Recovery. If you have one of those models, you can't reinstall 10.6 even from the original media, and Internet Recovery will not work either without the original owner's Apple ID. In that case, contact Apple Support, or take the machine to an Apple Store or another authorized service provider to have the OS installed.
    2. If you do own another Mac
    If you already own another Mac that was upgraded in the App Store to the version of OS X that you want to install, and if the new Mac is compatible with it, then you can install it. Use Recovery Disk Assistant to prepare a USB device, then start up the new Mac from it by holding down the C key at the startup chime. Alternatively, if you have a Time Machine backup of OS X 10.7.3 or later on an external hard drive (not a Time Capsule or other network device), you can start from that by holding down the option key and selecting it from the row of icons that appears. Note that if your other Mac was never upgraded in the App Store, you can't use this method.
    3. Partition and install OS X
    a. If you see a lock screen when trying to start up from installation media or in Recovery mode, then a firmware password was set by the previous owner, or the machine was remotely locked via iCloud. You'll either have to contact the owner or take the machine to an Apple Store or another service provider to be unlocked. You may be asked for proof of ownership.
    b. Launch Disk Utility and select the icon of the internal drive—not any of the volume icons nested beneath it. In the  Partition tab, select the default options: a GUID partition table with one data volume in Mac OS Extended (Journaled) format. This operation will permanently remove all existing data on the drive.
    c. An unusual problem may arise if all the following conditions apply:
              OS X 10.7 or later was installed by the previous owner
              The startup volume was encrypted with FileVault
              You're booted in Recovery mode (that is, not from a 10.6 installation disc)
    In that case, you won't be able to unlock the volume or partition the drive without the FileVault password. Ask for guidance or see this discussion.
    d. After partitioning, quit Disk Utility and run the OS X Installer. If you're installing a version of OS X acquired from the App Store, you will need the Apple ID and password that you used. When the installation is done, the system will automatically restart into the Setup Assistant, which will prompt you to transfer the data from another Mac, its backups, or from a Windows computer. If you have any data to transfer, this is usually the best time to do it.
    e. Run Software Update and install all available system updates from Apple. To upgrade to a major version of OS X newer than 10.6, get it from the Mac App Store. Note that you can't keep an upgraded version that was installed by the original owner. He or she can't legally transfer it to you, and without the Apple ID you won't be able to update it in Software Update or reinstall, if that becomes necessary. The same goes for any App Store products that the previous owner installed—you have to repurchase them.
    4. Other issues
    a. If the original owner "accepted" the bundled iLife applications (iPhoto, iMovie, and Garage Band) in the App Store so that he or she could update them, then they're irrevocably linked to that Apple ID and you won't be able to download them without buying them. Reportedly, Mac App Store Customer Service has sometimes issued redemption codes for these apps to second owners who asked.
    b. If the previous owner didn't deauthorize the computer in the iTunes Store under his Apple ID, you wont be able to  authorize it immediately under your ID. In that case, you'll either have to wait up to 90 days or contact iTunes Support.
    c. When trying to create a new iCloud account, you might get a failure message: "Account limit reached." Apple imposes a lifetime limit of three iCloud account setups per device. Erasing the device does not reset the limit. You can still use an iCloud account that was created on another device, but you won't be able to create a new one. Contact iCloud Support for more information. The setup limit doesn't apply to Apple ID accounts used for other services, such as the iTunes and Mac App Stores, or iMessage. You can create as many of those accounts as you like.

  • How to set up automatic payment for the purchase order

    Hi, All,
    I have one question how to set up automatically payment for the Rent Office purchase Order?
    There is the requirement from the client. They want to create one kind of purchase order for the Office Rent, then pay the fees in the certain time of every month to the vendor for the rent fees without any invoice. Whatu2019s the normal solution for this kind of purchase order? Is it ERS? Or something else?
    Please give me the details and business flow. Also please tell me how to setup in the SAP and T-code.
    Thanks in advance

    Either you can set up ERS or you can pay directly from the FI side.
    Prerequisites
    Evaluated receipt settlement must be flagged in the purchase order item.
    The vendor must be flagged as being subject to ERS in the vendor master record.
    The goods receipt must refer to a purchase order.
    Goods-receipt-based Invoice Verification must be defined for the purchase order item.
    A tax code must have been maintained in the purchase order item.
    The order price of the materials may not be an estimated price.
    If you flag a vendor as being subject to ERS, the system sets the ERS indicator as a default in each item when you create a purchase order for the vendor. You can prevent this happening for certain vendors by flagging the info record for the material and the vendor as not being subject to ERS.
    In Purchasing, you can delete the default ERS indicator in a purchase order item.
    Choose Logistics Invoice Verification ® Automatic Settlement ® Evaluated Receipt Settlement (ERS).
    The selection screen appears.
    You can use the following criteria to narrow down selection of the transactions to be settled:
    Company code
    Plant
    Goods receipt posting date
    Goods receipt document
    Fiscal year of the goods receipt
    Vendor
    Purchase order and order item
    You can define the selection criteria for the invoice documents by:
    Delivery
    Purchase order
    Purchase order item
    Goods receipt document
    Credit memo
    Invoice
    Currency
    Choose  Execute.
    The system issues a log for Evaluated Receipt Settlement, which displays the following:
    Settled
    In line with your selection criteria, the system displays all the order items that were settled (or if you are working in test mode, which would have been settled).
    Could not be settled
    In line with your selection criteria, the system displays all order items for which ERS is defined but could not be settled. It also lists the reasons.
    If the system reports being unable to invoice a transaction, you should exclude the transaction from ERS to avoid it being included in the log the next time ERS is run.
    Select the item and choose Exclude from ERS.
    The system also generates and possibly sends a message to inform the vendor(s) about the transaction settled, depending on the settings in Customizing.
    You can display the following environment information for the order items selected. To do this, choose Goto ®:
    Display purchase order
    Display invoice
    Display material document
    Display long text

  • Billing document cancellation (VF11) the cancelled doc. is not getting automatically cleared against the actual billing doc.

    Hi All,
    In case of billing document cancellation (VF11) the cancelled doc. is not getting automatically cleared against the actual billing doc. no. Each time user has to clear the doc. manually. We have observed this issue after recent patch updation dated 22nd Feb’2014. Till 21st Feb’2014 the cancelled doc. has been cleared automatically against their respective billing documents.
    Please guide.
    Thank you.

    Hi Gopi,
    Please chheck SAP Note No. 1259505. It explains two ways in which SAP releases cancellation documents to FI.
    OSS NOte 1259505 lists the possible causes from SD side &
