Is it possible to build Octave filter in LV?

Hello masterminds
I have a request for an noise measurement application being able to filter around a few select frequencies at 1 / oct bandwith. 
I know this is available in the sound and vibration tool kit, but adding such an expensive suite of tools to the project is not feasible for such a small feature.
I'm not a filtering guru. Is there anyone here who can point me in the direction of how to implement a simple filter with 1 oct bandwidth at a fixed frequency? Thank you in advance. 
Environment is LV 2012 on windows. 
Solved!
Go to Solution.

In the signal processing palette there is a butterworth filter.  Just set it to type bandpass and pass it a high frequency of 1.414 * center frequency and a low frequency of 0.707* center frequency.
You can try the other filter types tchebyshev etc if you want to play around with different phase responses.

    Hi Hans,
    I mean a filter for searching in your website. I give you a website and you see what I mean. I think i have to make a database for this to work.

  • Segment Builder create filter

    Within the Segment Builder (Refine button in Target Groups) you have the possibility to create a filter on attribute sets. The From field where you should choose the attributes is not a search field. Does anyone know how you can get this search field available?

    According to the course CR600 it is not possible to create filters.

  • Is it possible to build a project with Labview 2010 on a Windows XP system, that is useful for a system with windows 7 on it?

    Hi there,
    I am planning to use Labview 2010 in a short time.
    But before I'm going to use it I have some questions.
    I know it is possible to run Labview 2010 in an XP environment. But is it also possible to, when running Labview 2010 on a XP system, to build a project to a version that is useful in a Windows 7 environment?
    Or do I have to run Labview 2010, when I want to build a project that is useful on a Windows 7 system, on a system with Windows 7?
    Please give me some information.
    I hope to hear from one of you soon.

  • Drag and drop to build a filter?

    What do people think of the idea:
    Drag a photo or photos into the filter area to quickly build a filter?
    You could drag a photo into the date area to grab all of the photos by that date, or into the keyword area to grab all the keywords. Multiple photos could add either a AND or OR function to the set.

    Interesting concept! I like the idea!

  • Is it possible to build a binary working on solaris 8 from solaris 10

    Hi
    I understand that my requirement is kinda weird. However, I really wonder whether it is possible sometimes.
    I have built ssh successfully both on solaris 8 and solaris 10. Now the problem is the binary built on solaris 8 can work on solaris 10, but the binary built on solaris 10 can not work on solaris 8.
    The problem is SUNW_1.2.2 can not be found on solaris 8.
    $ldd sshd
            libresolv.so.2 =>        /usr/lib/libresolv.so.2
            librt.so.1 =>    /usr/lib/librt.so.1
            libsocket.so.1 =>        /usr/lib/libsocket.so.1
            libnsl.so.1 =>   /usr/lib/libnsl.so.1
            libc.so.1 =>     /usr/lib/libc.so.1
            libc.so.1 (SUNW_1.22) =>         (version not found)
            libdl.so.1 =>    /usr/lib/libdl.so.1
            libaio.so.1 =>   /usr/lib/libaio.so.1
            libmp.so.2 =>    /usr/lib/libmp.so.2
            /usr/platform/SUNW,Sun-Fire-V210/lib/libc_psr.so.1After more detailed investigation, I found the system-call dlopen and so on are linked to SUNW_1.2.2
    objdump -T sshd|grep SUNW_1.22
    00251240      DF *UND*  00000000  SUNW_1.22   dlerror
    00251510      DF *UND*  00000000  SUNW_1.22   dlclose

    0025181c      DF *UND*  00000000  SUNW_1.22   dlsym
    00251a98      DF *UND*  00000100  SUNW_1.22   unsetenvBut for the binary built on solaris 8, system-call dlopen is provided by SISCD_2.3.
    objdump -T sshd|grep dl      
    0023f160      DF *UND*  00000008  SISCD_2.3   dlopen

    0023f8d4      DF *UND*  00000008  SISCD_2.3   dlsymAs sshd from solaris 8 is working on solaris 10, I think SISCD2.3 is also available on Solaris10. So is it possible to build ssh (any special link option?) with SISCD_2.3 rather than SUNW_1.2.2?

    Build on 8, run on 8 through 10.

  • Is it possible to build a firewall using labview??

    Is it possible to build a firewall using labview??
    RAJESH

    There are several kinds of firewalls, for example:
    (1) so called "personal firewall software" which applies some policies to incoming and outgoing ethernet traffic on the computer it is running.
    (2) Dedicated hardware firewalls (having at least two ethernet interfaces) that enforce policies of traffic flowing across. These can be bridging, routing, or even be proxying.
    LabVIEW does NOT have access to the low level packet structure (ethernet header, ip header, tcp header, etc.) and relies on the OS for routing decisions. LabVIEW only deals with TCP and UDP and only at a very high level. A firewall must also make decisions for e.g. ICMP, GRE, or other IP packets, must know the status of all TCP flags (SYN, ACK, URG, PSH, FIN, RST), must check for valid fragmentations, et., etc.. LabVIEW cannot do any typical firewall tasks unless you do most of your work with external routines. In this case, LabVIEW just provides the UI.
    (Even simple ftp traffic would be quite complicated. For example the ports for the secondary data connections must be dynamically allowed based on information gleaned from the control connection, in this particular case the PORT command and the reply to the PASV command).
    I would say the answer is NO! Not with the networking tools provided with LabVIEW alone.
    With lots of work, you might be able to built a simple proxy server using LabVIEW, but this would seem quite useless...

  • Is that possible to build cube using STAGING FACT TABLE on Essbase ?????

    Is that possible to build cube using STAGING FACT TABLE on Essbase ?????
    If yes, kindly guide me to do ....
    Thanks in advance,
    Mehar

    I'm not sure what you are asking. IF you are asking if you can use a fact table as the source for buildnig an Essbase database, the answer is yes, from either SQL interface or Essbase Studio (or ODI or EIS). IF you are asking if you can use as relational staging table as an Essbase cube then no. If you can phrase the question differently or give an example of that you are trying to do, it might clarify what you are trying to do

  • Is it possible to build two different L2TP/IPSec tunnels per subnet or per user?

    Dear colleagues
    I wondered whether anyone could help with this one.
    Is it possible to build two different L2TP/IPSec tunnels per subnet or per user on a Cisco router or any other third party manufacturer?  The idea behind is to allow different access to resources to different support technicians.  Your help is much appreciated.

    Sure, the ASA can use LDAP/AD information to select what access list should be applied for that specific user or group of users logging into the VPN. You can use whats called DAP or just LDAP Attribute Maps.

  • Looking for an ASCII Art filter - possible to build from scratch?

    I would like an ASCII art filter for Final Cut Pro. The closest I have found so far is one for imovie from stupendous software (http://www.stupendous-software.com/).
    Does anyone know of one I've overlooked for Final Cut Pro?
    If not, do you think creating a filter using whatever ascii art generator's are already out there would be a worthwhile attempt for someone with little programming knowledge?

    Hi,
    Sorry, perhaps I should have been clearer! The function that I picked just to test what you need to do just happened to return a string that contains SPAN tags with style attributes. The actual function code is:
    create or replace FUNCTION out_string_fn
       RETURN VARCHAR2
    IS
       CURSOR emp_cur
       IS
          SELECT ename
            FROM emp;
       v_string   VARCHAR2 (4000);
    BEGIN
       v_string := ' ';
       FOR c IN emp_cur
       LOOP
          v_string :=
                v_string
             || '&lt;SPAN style="font-weight:bold;color:green"&gt;'
             || c.ename
             || '&lt;/SPAN&gt;'
             || ', &lt;/br&gt;&lt;/br&gt;';
       END LOOP;
       RETURN v_string;
    END;And this returned a naff list in green (see [http://apex.oracle.com/pls/otn/f?p=55041:57] and click the Test button) - but it does show that you can style the validation error messages

  • Is it possible to sort or filter the switch routes under the switching tab?

    In Teststand 3.1, is it possible to filter the switch routes under the switching tab in Action Properties?  Since I have a large amount of routes that have been created in Switch Executive, how can I filter out some of the routes from the "Routes to Connect" section?

    The TestStand Switching does not provide any inherent filtering capabilities.  You do have a couple of options, however.
    (1)  NI-Switch provides the ability to set up route connections in
    different groups.  The Switch Page in TestStand allows you to
    select Routing groups as well as specific Routes.  It may be
    easier for you to organize your Connections as groups and choose
    between different groups.
    (2)  The Property page also allows you to build route connection
    string and use that string  for your Switching actions.  It
    may be easier for you to build a Route string and easily change that
    string rather than selecting your routes everytime from within the
    TestStand window.
    Good Luck!

  • Is it possible to add a filter to a webapp without declaring it in web.xml

    Hello,
    I'd like to add a filter in my web.xml file, but without declaring it in my webapp.
    Indeed, I have multiple webapps, and I'd like to have a common web.xml file that should be directly included in all the webapps including this package ?
    Is it possible or not ?
    As for JSF, it is possible to add faces-config file by putting it in the META-INF of the package.
    Thanks in advance.
    bgOnline

    Your title and your question are opposites...
    A filter must be specified in a web.xml to be used. That doesn't mean the Filter's class HAS to be in your webapp, it just must be accessible to the Servlet container (you could place it in the common/classes directory or shared/classes directory or even the server/classes directory).
    I've not tried it, but I see no reason why you couldn't declare the filter and filter-mapping in the server's web.xml which would then filter all requests in all webapps.
    HTH.

  • Is it possible to build a "click to enlarge" option for images with Livecycle Designer?

    Hello! I have built an audit form where the auditors report conditions and add photos by using an image field that when clicked, gives them a dialog box to choose a picture. The photos initially just load as a small image on the screen - a little bigger than a thumbnail and just large enough so you can see what they're talking about. However, I'd like to add an option that would allow the reader to click (or do something) which would enlarge or zoom the image, and then return to its initial smaller size.
    I don't even know if it's possible and all my searching and reading hasn't come up with any solutions.  The best I can come up with as an alternative is to build some pages at the end of the audit report called "Photo Gallery" and use the global data option to sort of feed in whatever pictures are added into a larger image place on those gallery pages.  Not exactly what I was looking for, but at least it's a step in the right direction.
    Thanks for any ideas you might send my way!
    Jan

    Hi Jan,
    You could try having a custom dialog with a larger version of the image and then open the dialog when they click a button that covers the image on the form.
    Here is an example. https://sites.google.com/site/livecycledesignercookbooks/home/ClickToEnlarge.pdf?attredire cts=0&d=1
    The dialog code used in the example was generated using the method described here ... Adobe LiveCycle Designer Cookbooks by BR001: Using app.execDialog() in an Adobe Designer Form
    If your pictures are big then you will need another way of storing the image data, which is currently just a big JavaScript string literal, you'll see what I mean in the example.
    Regards
    Bruce
