• How to design a digital filter without addon Kit

  Hello

  I want to design a bandpass filter. Original signal is in analog form, ADC is used to convert the entries in the data digital n vice versa at the end of the output. How in labview 8.5 without addon Toolkit. Secondly how do I check the response of the filter according to these digital data, because by default, it gives the IMPULSE response, so how his will handle digital data...

  Thank you!!

  In the impulse response 1 sample is greater than zero, the rest is equal to zero. For the step response values are zero before the stage and not zero after the stage. To do this just make a table with the signal you want to use. But the table must be long enough to cover your analysis in the time domain. For example. I'm working now with digital phase sensitive detector. For this I use a sampling rate of 20 kHz, one of the last steps is an order of 3 Hz 20 filter low pass. To test the response of this filter, I needed at least 12 seconds of data. If the table that contains the data was 20000 * 12 samples

• How do I remove the filter from column of table without QueryEvent

  Hi all

  With the help of JDev 12.1.3.

  I have a table that contains a list of customers and suppliers like so.  Auto Repair Bob is a client.  Chips R Us is a seller.

  Name                | TypeKey (foreign key to the Table of Type) | Unique ID

  Auto repair Bob C 1

  Quickie Mart C 2

  R chips us V 3

  Let's say that I filter on 'V' through the user interface by selecting a choice selection of the column in the table.  Now only chips R Us opens.

  Name                | MasterTypeKey | Unique ID

  R chips us V 3

  Now, let's say that I want to remove my filter I can do another business process programmatically.  How to do that without requiring a QueryEvent and so to refresh a page?  I have been searching the various view classes of being variable Manager and have located the variable I need to remove it, but I'm not sure how to let him go.

          // get the query in it's current state
          String lQuery = bpIterator.getViewObject().getQuery();
          //get Valriables
          VariableValueManager lEnsureVariableManager = bpIterator.getViewObject().ensureVariableManager();
          Variable[] lVariables = lEnsureVariableManager.getVariables();
          int lCount = lEnsureVariableManager.getVariableCount();
          // Dump query
          System.out.println("---query--- " + lQuery);
          // if variables found dump them
          if (lCount > 0){
              System.out.println("---Variables:");
              for (int ii = 0; ii < lCount; ii++){
                  Object lObject = lEnsureVariableManager.getVariableValue(lVariables[ii]);
                  System.out.println("  --- Name: " + lVariables[ii].getName() + " Value: " +
                                     (lObject != null ?  lObject.toString() : "null"));
              }
          }  
  

  Makes me

  ---query--- SELECT BusinessPartners.COMPANY_ACCOUNT_ID,       BusinessPartners.MASTER_TYPE_KEY,         BusinessPartners.NAME,         BusinessPartners.BUSINESS_PARTNER_REF_KEY,      FROM BUSINESS_PARTNERS BusinessPartners WHERE ( ( ( (UPPER(BusinessPartners.MASTER_TYPE_KEY) = UPPER(:vc_temp_1) ) ) ) ) AND BusinessPartners.COMPANY_ACCOUNT_ID = :Bind_CompanyAccountId ORDER BY BusinessPartners.NAME
  ---Variables:
    --- Name: vc_temp_1 Value: C
    --- Name: pCompanyAccountId Value: null
  

  I am trying to get vc_temp_1 is deleted or to accept any value, but when I write what follows I get an error message "missing parameter IN or OUT."

  lEnsureVariableManager.removeVariable("vc_temp_1");
  

  Any ideas on how I can remove the filter on my view object?

  It cannot work without running the query again. As you see that the filter is running a query make the vo is not all data.even if you delete the variable filter, that you do not get the data from the database you need to show.

  You can reset the filter (see https://tompeez.wordpress.com/2013/08/06/jdev-12c-how-to-reset-a-filter-on-an-aftable-the-12c-way/) but you must run the query again to the corresponding data.

• How to get Dolby Digital 5.1 sound on Qosmio?

  I wonder how to sound Dolby Digital 5.1 Qosmio. Whenever I play an original DVD movie, all I can get is Dolby Prologic 2. Have a link with DRM? I use Thomson mini plug opto cable. Home Theater receiver accepts digital input but does not have 5.1 sound. The movies that I download with DRM removed HD forums gives the same results. Where is the problem?
  Thank you

  Hello

  The line line and S/PDIF audio headset uses the same output.

  It is possible to connect the audio/video receiver via SPDIF optical cable.

  Hello

  You can create a Windows 7 installation disc yourself - just download the good Disk Image ( must be the same version that originally came with your laptop - IE Windows 7 Home Premium 64-bit ) from the link below and use an app like ImgBurn to burn the ISO correctly on a blank DVD - a guide on the use of ImgBurn to write an ISO on a disc is here.  These Images are clean and a well respected source, however there are only limited versions available.

  Windows 7 sp1-iso-official-32-bit-and-64-bit

  Use the disk to perform the installation, enter the activation key of Windows on the label of the COA at the request and once the installation is complete, use ' 'phone Method' described in detail in the link below to activate the operating system -this made method supported by Microsoft and is popular with people who want to just have a new installation of Windows 7 without additional software load normally comes with OEM installations.

• Digital filter on the sample clock 6601/6250

  Hello

  I use a PCI-6601 (Dev1) and the card PCI-6250 (Dev2) connected via a cable RTSI.

  I apply a PWM signal to the 6601 ctr0 (Dev1 / / PFI38) and activate the digital filtering (100 ns) on the respective task (measure of the period).

  I apply an analogue signal to AI0 map of 6250. As I am interested in a sample of analog measurement when the PWM signal changes from low to high, I put the clock sample of the AI task source ' Dev1 / / PFI38 "and the side assets of clock sample"Insurrection. "

  Everything works fine, but I have a question:

  The sample for the AI clock is the task the filtered PWM signal or not filtered PWM signal?

  Kind regards

  Udo

  Hi Udo,

  Great question!  Digital filters are actually not part of the subsystem of counter, but rather the line itself PFI.  So, if you have activated the digital filter for a specific line of the PFI, the signal that you route to any subsystem of the PFI line will have already crossed the filter.

  It's actually the workaround to the PFI filters on M-series / TIO DAQ devices when you are not using meter (materials of filtering on each PFI line but the DAQmx driver allows only the filtering part of duties of counter on these devices).

  I also wanted to emphasize that the 6250 itself has 2 onboard counters, then you could do the same thing using just the 6250 (unless you use more than 2 meters).  I hope this helps!

  Best regards

• SMU-5451. digital filter Interpolation

  Hello

  I use the SMU-5451 with FPGA SMU-7966R signal generator. They are related to peer-to-peer technology.

  I want to use the digital filter of Interoplation, but there is a place to errors in the property node. Here is a screen of this error.

  What should I do to fix this?

  Looks like the 5451 doesn't have a digital interpolation filter.  There is only a FIR filter on the device.  You can check that this is the case and that the problem is not the use P2P when trying to run a script example that does not use P2P and setting this property.  You should get the same error.

• digital filter 4474

  I use a card PCI-4474 sampling rate maximum of 102400 Hz

  One of the 4 analog inputs is TTL signal for the timestamp: see exhibit attached with the number the horizontal sample [#] and vertical supply voltage [V].

  The swing before the front, it seems as if a digital filter is applied in this forum.

  With the other signs of my request, there is no margin of time for these oscillations before the face steep.

  Y at - it an option to disable this feature? (that's my assumption is correct: disable the digital filter?)

  I'm with LabWindows CVI with DAQmx

  I use Windows 7 x 64

  Kind regards, Jos

  Yes, it's because of an internal filter.

  No, there is no option to turn it off.  It is inherent to all NI DSA devices.  See this article for more information.

• How to use the digital pen on W700 (Win 8 version)

  Expert HE,

  How to add the digital pen for W700 with my digital "BAMBOO PEN - CTL-470' pen?

  or I buy Acer digital pen?

  Thank you

  A pen that works with a bamboo tablet is not compatible with the W700. Pens like that (fine point, sensitive to pressure, etc.) require what is called an active digitizer, which does not have the W700.

  You can use an inexpensive capacitive stylus like those that are advertised for the iPad and the iPhone, but those who are actually just a substitute for finger; the contact surface is a bit smaller and so maybe a little more specific than the finger and you will find perhaps more comfortable, but it does not add capacity.
