Help in Freq Modulation and demodulation

Hi,
I was asked to design Frequency modulation and demodulations without using modulation tool kits.
I some how managed to construct frequency modulation, i also got the output.
But if the graphs are observed, we can c that message signal is in between 0 to 0.1 whereas the time domain output is varying between 0 to 10000.
I need help in this issue and also demodulating the same.
I had no clue of labview when i started.
I have to complete by 10th Nov .. Plz help.
I am attaching the vi file.
Thanks

How to use Generate Synchronization Parameters for PSK modulation and demodulation

Hi I am trying to use Generate Synchronization Parameters.vi to sync the recovered stream after demodulation and my input stream to modualtion block but I don't know how to work with this block to sync input stream with output stream. Also would you please let me know what are the ways to sync input bits and demodulation bit stream.I really appreciated your help
Thanks
Solved!
Go to Solution.

Hi en99,
In order to use "MT Generate Synchronization Parameters.vi" you must wire in the following on your block diagram:
The system parameters created in "MT Generate System Parameters.vi" needs to be wired directly to the sync vi.
The synchronization parameters need to be wired direct to "MT Demodulate.vi"
The synchronization bits can be wired into the sync vi direct from "MT Generate Bits.vi"
What I have done is taken your 11.vi that you uploaded in your previous post and altered it to contain the sync vi. I have saved it as a 2010 version.
I hope this information helps!

Mfsk Digital modulation and demodulation

I'm having problem doing a MFSK which critera are enter binary bit and able to produce different frequencies and able to show "combined" waveform of different frequency. at least 8-ary FSK (MFSK) . Hope some one can help me to create such .VI file. Thank you.

Good morning my friend, sorry if i misleading you as english is my weakest language. Actually i just need a simulate wave form of MFSK with controllable integer in labview 6.8. (kind of old ver heheh.. lol) criteria as below.: Just able to click run any show the modulated wave form. (combined of 8 different frequencies) (digital will be good) I attached an analog style of mfsk (failure circuit)
8-ary FSK
show square wave with controllable binary
show 8-FSK sine wave tally to the binary when controlling the square wave. (meaning modulated wave form)

Want help in creating pov and poh in module pool

i want to create process on help and process on value request.

can u please send me this information also.
i am new to screen programming .

krishna,
For POV
Input Help in Dialog Modules
You can call dialog modules in the POV event using the event keyword PROCESS ON VALUE-REQUEST.
PROCESS ON VALUE-REQUEST.
FIELD are not available, since it is not transported by the FIELD statement during the PROCESS ON HELP-REQUEST event. You can now program your own value lists in the module. However, this procedure is only recommended if it really is not possible to use a search help. Defining search helps is much easier than PROCESS ON VALUE-REQUEST, since the system takes over some of the standard operations, such as getting field contents from the screen. It also ensures that the F4 help has a uniform look and feel throughout the system. Furthermore, it means that you do not have to reassign input help to fields on each screen.
Despite the introduction of search helps (and search help exits), there are still cases in which you need to use parts of the standard F4 functions directly. In this case, there are some standard function modules that you can use in the POV event. They support search helps, as well as all other kinds of input help, and are responsible for data transport between the screen and the input help. These all have the prefix F4IF_. The most important are:
F4IF_FIELD_VALUE_REQUEST
Calls the input help of the ABAP Dictionary dynamically. You can pass the component names of a structure or database table of the ABAP Dictionary to the function module in the import parameters TABNAME and FIELDNAME. The function module starts the ABAP Dictionary input help for this component. All of the relevant screen fields are read. If you specify the import parameters DYNPPROG, DYNPNR, and DYNPROFIELD, the users selection is returned to the corresponding field on the screen. If you specify the table parameter RETURN_TAB, the selection is returned into the table instead.
F4IF_INT_TABLE_VALUE_REQUEST
This function module displays a value list that you created in an ABAP program. The value list is passed to the function module as the table parameter VALUE_TAB. If you specify the import parameters DYNPPROG, DYNPNR, and DYNPROFIELD, the users selection is returned to the corresponding field on the screen. If you specify the table parameter RETURN_TAB, the selection is returned into the table instead.
There are also two function modules - DYNP_VALUES_READ and DYNP_VALUES_UPDATE - that can read the values of screen fields and return values to them during the POV event. For further information, refer to the relevant function module documentation.

The next screen (statically defined) for screen 100 is itself. It has the following layout:
The input fields have been adopted from the program fields CARRIER and CONNECTION. The pushbutton has the function code CANCEL with function type E.
The screen flow logic is as follows:
PROCESS BEFORE OUTPUT.
MODULE INIT.
PROCESS AFTER INPUT.
MODULE CANCEL AT EXIT-COMMAND.
PROCESS ON VALUE-REQUEST.
FIELD CARRIER MODULE VALUE_CARRIER.
FIELD CONNECTION MODULE VALUE_CONNECTION.
When the user chooses input help for the individual fields, the following is displayed:
For the Airline field, the POV module VALUE_CARRIER is called. The function module F4IF_FIELD_VALUE_REQUEST displays the input help for the component CARRIER1 of the structure DEMOF4HELP from the ABAP Dictionary, namely the search help DEMOF4DE. The users selection is returned to the screen field CARRIER.
For the Flight number field, the POV module VALUE_CONNECTION is called. The function module DYNP_VALUE_READ transports the value of the screen field CARRIER into the program. The program then reads the corresponding values from the database table SPFLI into the internal table VALUES_TAB using a SELECT statement, and passes the internal table to F4IF_INT_TABLE_VALUE_REQUEST. This displays the internal table as input help, and places the users selection into the screen field CONNECTION.
For POH
Field Help
There are three ways of displaying field help for screen elements:
Data Element Documentation
If you place a field on the screen in the Screen Painter by copying a ABAP Dictionary field, the corresponding data element documentation from the ABAP Dictionary is automatically displayed when the user chooses field help (as long as the help has not been overridden in the screen flow logic).
For further information about creating data element documentation, refer to data elements.
Data Element Supplement Documentation
If the data element documentation is insufficient, you can expand it by writing a data element supplement
Data element supplement documentation contains the heading Definition, as well as the following others:
Use
Procedure
Examples
Dependencies
To create data element supplement documentation for a screen, choose Goto ® Documentation ® DE supplement doc. from the element list of the screen. A dialog box appears in which the system proposes a number as the identified for the data element supplement. You can then enter help texts for the above headings using the SAPscript editor.
Data element supplement documentation created in this way is program- and screen-specific. Any data element supplement documentation created in the ABAP Dictionary with the same number is overridden by the screen-specific documentation. You can link existing data element supplement documentation created in the ABAP Dictionary with a screen field by using the table THLPF. To do this, crate a new row in THLPF containing the following data: Program name, screen name, field name, and number of the data element supplement documentation.
To display data element supplement documentation, you must code the following screen flow logic in the POH event:
PROCESS ON HELP-REQUEST.
FIELD is defined in the ABAP program like a normal PAI module. The processing logic of the module must ensure that adequate help is displayed for the field in question. Instead of calling an extra screen with text fields, you should use one of the following function modules to display a suitable SAPscript document:
HELP_OBJECT_SHOW_FOR_FIELD
This function module displays the data element documentation for components of any structure or database table from the ABAP Dictionary. You pass the name of the component and structure or table to the import parameters FIELD and TABLE.
HELP_OBJECT_SHOW
Use this function module to display any SAPscript document. You must pass the document class (for example, TX for general texts, DE for data element documentation) and the name of the document to the import parameters DOKCLASS and DOKNAME. For technical reasons, you must also pass an empty internal table with the line type TLINE to the tables parameter of the function module.
For further information about how to create SAPscript documents, refer to the Documentation of System Objects documentation.

The next screen (statically defined) for screen 100 is 100. It has the following layout:
The screen fields DEMOf1HELP-FIELD1 and DEMOF1HELP-FIELD2 from the ABAP Dictionary and the program fields FIELD3 and FIELD4 are assigned to the input fields. The pushbutton has the function code CANCEL with function type E.
The screen flow logic is as follows:
PROCESS BEFORE OUTPUT.
PROCESS AFTER INPUT.
MODULE CANCEL AT EXIT-COMMAND.
PROCESS ON HELP-REQUEST.
FIELD DEMOF1HELP-FIELD2 MODULE F1_HELP_FIELD2 WITH VAR.
FIELD FIELD3 MODULE F1_HELP_FIELD3.
FIELD FIELD4 MODULE F1_HELP_FIELD4.
The components FIELD1 and FIELD2 of structure DEMOF1HELP both refer to the data element DEMOF1TYPE. This data element is documented, and also has two supplements with numbers 0100 and 0200.
The following field help is displayed:
When the user chooses F1 on the input field for DEMOF1HELP-FIELD1, the data element documentation for DEMOF1TYPE is displayed, since the field does not occur in the PROCESS ON HELP-REQUEST event.
If the user chooses F1 repeatedly for the input field DEMOF1HELP-FIELD2, the data element documentation is displayed, along with the supplement documentation for either 0100 or 0200 alternately. The variable VAR is filled in the dialog module F1_HELP_FIELD2.
When the user chooses F1 on the input field for FIELD3, the data element documentation for DEMOF1TYPE is displayed, since this is called in the dialog module F1_HELP_FIELD3 by the function module HELP_OBJECT_SHOW_FOR_FIELD.
When the user chooses F1 on the input field for FIELD4, the SAPscript documentation DEMO_FOR_F1_HELP is displayed, since this is called in the dialog module F1_HELP_FIELD4 by the function module HELP_OBJECT.

Creating Help for multiple modules, multiple versions and multiple locales

I need to put together a new help solution for a suite of applications. The problem I have is working out how to manage and publish the content. Would someone be able to offer any advice?
The software has:
Multiple modules
Head office and site versions
UK and US locales
Multiple software versions to be supported
Previously I used WinHelp, regenerating the project 6 times per software version to provide all possible permutations.
I’d like to create a single hosted help solution with a simple home/landing page that allows users to enter a natural search term – the results provided would be drawn from the database or collection of available help topics and ranked for relevance to application/version/locale etc.
Obviously the right help must be displayed, and I don’t want every topic to be prefixed with: [uk | head office | Module name | v3.5].
I have RH9 (for html and word), but would upgrade if I needed to.
I have looked into using Webhelp, Airhelp and even Wordpress but still haven’t worked out the best way to do this. I understand that this is not a normal posting, but if anyone can point me towards any information that may help me I’d very much appreciate it.

I think build expressions are what I am looking for, but if I need to create a new conditional build tag for every variation (Locale/Installation/Version) it will be become rather unwieldy and since new software versions are released almost quarterly it will soon become challenging to manage.
OK, I am happy you picked up on that point. It will be challenging.
Sorry but your requirement is a complex output so too will be the solution.
Also, can I apply a build tag to an entire topic to include or exclude it from a build for whole topics that are UK or US specific?
Yes. Whole topics or content can be tagged. You can apply a topic tag to exclude it entirely from some categories and you can have content tags so that variants of the topic can be generated so that a topic could be excluded from US but for UK it could then vary according to version, for example.
From an authoring perspective I want to create a single help file, but I can’t have users scrolling through hundreds of possible help permutations to find the one they are looking for. Creating one help file will simplify the hosting of the webhelp too.
You cannot have sub categories so you would create a category for each permutation. I don't think that would amount to hundreds though.
Another approach would be similar tagging but using multiple layouts. With categories, your output would have a folder for each category and when a user selects what they want, the system goes to the chosen folder. If you created multiple layouts, you would have much the same folders but each one would be a standalone help system. It would be for your developers to install the right help for each user. Not as difficult as it might sound. For a start, the versions would be simple to hook up.
A lot of places stop updating help once either a new version is released or goes out of support.
The best advice I can give is cut down the permutations as much as you can.

Problem with modules and ModuleLoader

Hi everybody,
i'm facing a real funny problem with modules and
moduleLoader, i hope
it's not (only) my fault anyway...
If i create a normal flex project with fBuilder, i'm able to
use
modules in a lot of different ways (as mxml, as as in a
function etc..)...
but if i try to use them in my fds application (created with
fds
eclipse plugin or as a dataServices project) i can't use
modules. The compile-time error message is
always the same:
Could not resolve <mx:ModuleLoader> to a component
implementation
I tried a lot of solutions, paying attention to import all
the classes, to declaration, naming, positioning
etc...but nothing changes, this thing is drivining me
crazy!!!.
I will appreciate anykind of help.
TIA
Fabio

Any idea?

SAP R/3 Modules and transactions belonging to them.

Hello there,
I have two questions which I would like some help with:
Q1 Is there a link to documentation that lists all the SAP R/3 functional modules and provides an overview/description of each module?
Q2 I would like to list all the transactions belonging to a fuctional module/area such as SD, MM, PM, FI/CO etc. I know that tables TSTC & TSTCT will provide a list of all the transaction codes, but is there a table that will show all transaction codes belonging to a specific fuctional module?.. if not then is there another way of getting this information?...Please bear in mind that I need to be able to download this information to an excel spreadsheet.
Your help here would be much appreciated.
Many thanks
Sharon

Photos in Library module and after export look different than in Development module

Hello,
I experience a problem.
After I update photos in the Development module, the updates seem not to be shown in the Library module. And when I subsequently export to Flickr, Flickr is also showing the original photo, not the adapted one.
I noticed this the first time after making Blacks a bit deeper, causing a sunflower to become a deeper yellow. I thought that my adaptations were not applied in the Library module. After I checked with cranking down the Saturation all the way back (to almost black-and-white), that adaptation WAS applied in the Library view. So it had to be something else, causing the same color difference between the Library and Development modules.
When I switch from the Library module to the Development module, I see a slight delay in applying my changes, but they are applied. Before they are applied, I can see that the original photo is shown and that looks the same as in the Library module and on Flickr.
The photostrip on the bottom of the Lightroom screen also shows the original photos only, unless I go to the development module and select a photo (adaptations are applied in the photostrip after I select the photo, not before).
After I played a bit more in the Development module, I found something strange in the Camera Calibration menu of the Development module. The Adobe Profile (my default) caused an obvious color difference between the Library (less saturated) and the Development (more saturated) modules. The Camera Standard profile also showed a (very) slight difference, but I was unable to notice the differences using the other profiles.
So I was thinking (but it's only a guess), that the profiles are not applied in the Library view and on export, but they are in the Development module?
I use Lightroom 5.6, Camera RAW 8.6.
Please help me, as this is very annoying. I currently cannot export my photos to Flickr or anywhere else, unless I overcompensate before exporting. And I really don't want to do that. My Lightroom photo is my perfect photo, and I want to keep it that way...
Many thanks in advance for any help,
Peter

Hi ssprengel,
Thanks for your reply. Let me react to each possibility you mention and provide some extra information.
- "Check your Export / File Settings / Image Format and make sure they are set to JPG not Original". Done that, it's not on Original, but on jpg. This would not explain why I see the difference in the Library and Development modules, by the way. But better to know for sure.
- "...the most likely thing that is wrong is your color-management on your computer is not working properly". It is a PC with Windows 7. I have been using Lightroom for maybe 6 years and I never had this problem before. The last time I changed my setup is more than a year ago and this problem only started to happen a short while ago (after the update to Lightroom 5.6? I'm not sure, but that's the only thing that has changed lately). I use a Spider to create a custom profile that is correct for my setup and do a regular update on the profile.
- "what brand and model of monitor do you have?" I have an EIZO FlexScan S2411W and use that for a long time as well. I chose this brand of monitors for its good color reproduction and I have been happy with it for years now.
What I am not getting is why would all this show a difference between the Library and Development module? The only difference is the Lightroom software that is switching from one module to another, and that should deliver the same photo. I'm also stating in my first post that the differences are very noticeable using the Adobe Standard Camera Profile in the Development module. I have a feeling that the profile is part of the problem.

Calling search helps dynamically in module pool program

Hi Experts,
I have created two search helps. I need to call these search helps in my module pool program dynamically for a single field (i.e ZMATNR).
you might be known... if it is a single search help, we can assign that in field attributes.
But here... I need to call different search helps for a single field based on the condition.
Pls help me.
Thanks
Raghu

Hi,
Use the below function module and pass the search help created in search help field according to the condition.
Process on Value-request.
if condition = A.
call function " F4IF_FIELD_VALUE_REQUEST"
TABNAME           =
FIELDNAME        =
SEARCHHELP     = "Mention search help created
Elseif Conditon =B.
call function " F4IF_FIELD_VALUE_REQUEST"
TABNAME           =
FIELDNAME        =
SEARCHHELP     = "Mention search help created
Endif.
