Is it possible to build the filter of the Octave in LV?

Hello brains

I have a request for application of noise measurement is to filter around a few select frequencies at 1 / oct bandwidth.

I know it's available in the kit of audio tools and vibrations, but add such an expensive suite of tools for the project is not feasible for such a small feature.

I'm not a filtering guru. Y at - there someone here who can point me in the direction of how to implement a simple filter with bandwidth of 1 oct to a fixed frequency? Thank you in advance.

The environment is LV 2012 on windows.

In the range of signal processing, there are a butterworth filter.  Place it just type bandpass and pass it a high frequency of 1.414 * center frequency and a low frequency of the frequency of 0.707*.

You can try the other types filter tchebyshev etc if you want to play with the responses of different phase.

  • JET license check: is it possible to build the customer facing app using JET + ADF on weblogic today?

    Hello, our company uses under license server Weblogic 12 c and we use now ADF 12 c. We are allowed to use the JET to build a small client demand on top of Weblogic + ADF? (This is not an internal app; we have not begun to use Oracle cloud)

    I know that this is not allowed today. She is permitted after JET is accessible to the public. I want to double confirm my interpretation, thanks a lot!

    Hello

    You are correct in your assumptions.  Today, you need an Oracle Cloud license to distribute a production application using Oracle JET.

    We'll be open sourcing Oracle JET very soon however.

    Do you have a rough idea of when you want to go production with your application?

    Why is - this happens when I open documents using Mac advertising agency and I'm on PC?

    Hi Mikael,

    files have been archived in archive zip-file when transferred via the ftp protocol? I guess, not.

    If the files were already placed in a document, InDesign on the agency side the following workflow might be the solution:

    Office on Mac OSX:

    1 package the InDesign document, as well as placed images and fonts of the necessary document with InDesign packing device.

    2. the folder packed in a zip zip file.

    3. download the zip file to an ftp server

    You on Windows:

    1. download the zipfile to your own workload.

    2 unzip the zip on your workload. Do not delete the zip file.

    3. rename the folder of the package to fit your scheme of naming of jobs (option)

    4 rename the InDesign document to adapt to your schema naming of jobs (option)

    5. open the InDesign file in the packed file.

    Do not move or save somewhere else.

    Alternative:

    Work with Dropbox to share documents on a shared volume of Dropbox, if documents must move forward and backward between you and the Agency.

    Another option would be to use my script which samples an image and apply colors to a model with deco fill script. It's a little slow to use, as it has made a lot of samples, but you can do interesting things with it. Works on CS6 and higher:

    You need create a clear color model to do this. Here is a sample using a cross stitch pattern:

  • Is it possible to export the html code of a muse site I'm building?

    Is it possible to export the html code of a muse site I'm building?

    Mac_Heibu has the right idea. When you export your site in HTML format, it creates a folder containing all of your pages. Here is an example of what the file contains. All of your HTML pages, all of your scripts, CSS, code and it will also have individual files IN your main folder of your phone or Tablet versions, as appropriate. This method allows you to upload your files to an FTP host. However, if you try to upload to an FTP server, the BEST solution would be to go file > load on the FTP host. If this helped you, please mark the correct answer in the answer of mac_heibu and don't hesitate to mark my answer as a useful answer.

  • Is it possible to customize the sensitive presentation - sequence of the table of contents, Index, tabs filter?

    Hello

    I use RoboHelp 2015 and reactive production layout, I need to rearrange these tabs. I want the tab of filtering of dynamic content to be displayed before the table of contents.

    Is it possible to re - sequence tab filters before tab table of contents by making some backend work in CSS or code?

    forum post.png

    Or the other way improved - if we select filters say - sales, then sales related subjects should be displayed (rather extended below - just like the expansion of text).

    Is it possible to customize the sensitive provision in this way?

  • Is it possible to build an application with CS5.5 which can run in the old iPod

    Hello

    Anyone know if there is a way to build an application with flash CS5.5 which can run in the old iPod?, as with CS5?

    Impossible to install every IPA I build with CS5.5 in my iPod 8 GB with iOS 4.2 and before with CS5, I could install all OPI it and test.

    The lack of support for the 8 GB iPod would be limiting for the market and sales...

    Is there some settings to build the IPA for older iPods?

    Thank you

    An easy solution for your need must keep a copy of CS5 installed and use it to support older devices. A harder solution is to keep a copy of the PFI of CS5 and use the command line to compile applications with CS5.5. You will not be able to perform one of the novelties of CS5.5, and you need to manually change the descriptor XML to ensure that it is compatible with PFI.

    Like I said, keeping CS5 autour would be the easiest solution.

  • Application builder cannot build the exe. Error 8 has occurred in AB_EXE.lvclass:Build.vi-> AB_Build.lvclass:Build_from_Wizard.vi

    I bought a new Dell laptop (Windows 10 Pro) and LV 2015 (32-bit) is installed. I copied my project files and tried to build the exe file and received the error 8. After much searching for an answer, I created a minimal test with just a single white vi project and an exe based build spec to reproduce the error with. Whenever I try to build, I get the same error 8:

    An error occurred during the generation of the application. You don't have the appropriate permissions to create the application at the specified location, or the application is in use.

    Invoke the node in AB_Engine_Build_Method_Wrapper.vi-> AB_EXE.lvclass:Build.vi-> AB_Build.lvclass:Build_from_Wizard.vi-> AB_UI_Frmwk_Build.lvclass:Build.vi-> AB_UI_FRAMEWORK.vi-> AB_Item_OnDoProperties.vi-> AB_Item_OnDoProperties.vi.ProxyCaller

    Method name: Build: Application

    Error 8 has occurred to AB_EXE.lvclass:Build.vi-> AB_Build.lvclass:Build_from_Wizard.vi

    Possible reasons:

    LabVIEW: File permission error. You do not have the correct permissions for the file.

    I can't quite imagine I could have permissions issues. I of course have full admin on the machine privileges.

    I've seen other messages (like this one) who speak to have Windows Explorer opened the path of construction when it tries to go up and get this error. I made double sure that I don't have ANY Windows Open Windows Explorer, trying to build. There was a mention in one of the positions which perhaps of LabVIEW in current directory is defined in the file generation, but I'm not quite what that means, or why that might happen when there isn't usually prevents me to build on other machines.

    I tried the procedure described in the KB, but no help.

    Interestingly, I have created a virtual machine (Win 10) for a different project and installed LV 2015 32 bits in the virtual machine, and all my applications build very well in the virtual machine. But on OS from my physical machine, I get this error 8 for all construction applications.

    I tried to fix LabVIEW, and also I tried to uninstall reinstall LabVIEW. Nor was the error to go away completely. After the repair, the project has successfully generated once. But subsequent attempts to build fail with the same error.

    See the attached test project and the build log.

    My best guess is that some external process is the use of the folder and do not let you write here. The most likely candidates are anti-virus software or a service of indexation of a certain type. I'm guessing that he sometimes managed everything simply because it is a race condition and in these cases, the blocking part yet or is already done.

    You could try the building to a network drive, when these forces are less likely to be able to make the lock or you could try to find a software that shows you what software has handles opened in a folder and control for an offender. I seem to remember that the Process Explorer and SIW show this, but it's far from my area of expertise.

  • Is it possible to use the internal clock for meter tasks in the buffer?

    Hello

    Hardware: USB term mass 6251

    Software: LabView 2011 SP1

    I need to measure the angular lever position and speed of a carpet. For that I use two quadrature encoders. To accurately calculate the speed I use buffered from the measures of position using one of the available onboard counters. I understand that for this technique, I provide a sample for the meter clock. I wonder if it is possible to use the internal time base. Note that both of my counters are used so I can't generate a signal to clock with them.

    I found two conflicting pages related to my problem:

    1) http://digital.ni.com/public.nsf/allkb/EA7FFFEAFC3E1D85862572F700699530

    2) http://digital.ni.com/public.nsf/allkb/775290A3121D1FFC862577140074D3B3

    The first says that I can use the internal clock of 100 kHz, and the other says that I have an external clock.

    Comments/solutions?

    Javad

    Hi Javad,

    On your specific device, there is not a direct route from the time base of 100 kHz for the meter (according to the routing table of MAX):

    Yellow cell indicates that a route is possible but there is not direct (the "gate" terminal is used as sample clock for counters of the M series).  Mouse on the cell reveals yellow that make this route really requires the use of a counter (so it is not suitable for your application).

    On the line above "100kHzTimebase" you will notice it is called 'FrequencyOutput', which does not have a direct route to the door.  This would be the way to go if you want to route 100 kHz (or some other frequency) as your sample counter clock - you can set it up the same way to a standard meter output task:

    The output frequency doesn't have that many features like a meter output, but it is able to generate a continuous stable frequency.  There are only 32 different frequencies that can be generated using Freq Out on the 6251:

    {10 MHz, 100 kHz} / {01:16}

    Do not forget that the resolution of your measure of frequency by using this method will be equal to how many times you update the measure (hopefully, that makes sense).  In other words, if at the end of all the 1 second, you take the total number of charges since the last second, you would have a 1 per second equal resolution change in the number.  If you take the difference twice per second, you would end up with half the resolution.  You will be sampling the account register fairly quickly, but you will need only to do the calculation of the frequency after that all N samples in order to obtain a significant number.

    Another method that will certainly give a higher resolution in less time at typical speeds of coders is to set up a measurement of the frequency (the counter will count the internal 80 MHz base time period your external signal and the pilot calculates the frequency based on the result).  This method uses only a single entry - so you can just feed the 'A' your encoder quadrature signal (the method will not work if you are interested in absolute position or direction).  Without using signals A and B together, you will be susceptible to noise (which is common to have a quadrature encoder) that you want to delete (perhaps by setting up a digital filter).  Finally, you want to set a reasonable timeout on your reader calls (which will be blocked until a period of your external signal occurs), and the error-200284 handle simply report "0Hz" to make sure that your program is still sensitive even without an external signal present.

    Best regards

  • Is PAP2T possible to spend the first dialled digits?

    I have a dialler of Mitel to use my old phone pulse, but it is blocked for programming, if I dial 4321, he composed a long number transfer th 4321. Is it possible change the dialplan to ignore these digits, and onle build the rest? If so, how should I do this?

    d_s_k

    PS

    No composition first and foremost what I compose is: 131 break 1234567890 if I dial it 4321 sends 131 1234567890 4321

    DS

    If the number he composed is fixed, then you can be stripped out with the numbering plan

    Add something like this to your dial plan

    | <>xx.|

    Depending on the duration of the break after the 131, you need to increase the short interdigit timer so the numbering plan may not expire before he gets to the number after the 131.  The default short interdigit timer is 3 seconds.

    Edit: You can increase the short interdigit timer with an expression before the dial plan: S6:, ( <> xx |...) would increase the short interdigit timer at 6 seconds.
