Decimation( Does decimation.vi have a low pass filter?)

Hello,
    I have a question regarding decimation function (decimation(continuous).vi) in labview. Does it have a low pass filter to take care of aliasing, if yes is it a zero phase filter. Basically I am looking for some thing which can decimate 20KHz sampled signals to 5KHz.
Thanks,
kartik

Depends on your LabVIEW version and installed toolkits. 
The Digital Filter Design Toolkit  has a decimation VI that includes a LP AA filter.  Open the LabVIEW Help and search for 'decimation' and 'filter' to see what tools are available.

  • Does scc sg04 have low pass filter?

    Hi.. I am using SCC-SG04 for full bridge strain gauge with SC2345. I found the voltage output on oscilloscope with much noises when I directly measured from SCB 68 output which linked with SC2345.
    High frequency noises was reduced a lot when I used simple passive RC low pass filter circuit. (cutoff freq is 1kHz) But there are still noises. Voltage excitation 2.5V and gauge resistor values are 120 ohms.
    Therefore, I wish that is there any filter in SCC SG04? I found that  manual described it has 1.6kHz LP filter. Actually I am not sure what my cutoff freq should be and I think there should be less noise if SCC SG04 has LP filter. Am I right?
    I would like to use DAQ in PC and I don't know which suitable hardware to use. I already have Labview 8.
    Please reply me.
    Thanks.
    Myo

    Hello myo,
    First off, welcome to the NI forum.  To answer your question, yes there
    is a 1.6kHz RC low pass filter on the SCC-SG04 module.  I am unsure why
    you are getting noise when you measure the signal directly, however there are several possibilities.  The most likely of which is since the
    device is not attached to a DAQ card (as it usually is), there may be
    some grounding issues, the device may not be powered correctly, or some
    other issue related to connecting the devices together.
    The type of DAQ cards we usually reccomend for use with the SC 2345 are our E series or M series cards. You can use the SCC Advisor to help you choose as well. If you already have some HW, just choose what you have; It will be included in a quote, but you can use the advisor to see which HW works with the rest of your setup.  Some of these cards have hardware filters as well, and you may be able to do some filtering in software.
    If you are looking to purchase a DAQ card for your computer, I suggest calling or emailing our sales department, especially if you want more information about the different cards we offer.

  • What does the Low-Pass filter do (for dummies)

    Dear colleagues,
    I'm about to encode a lot of content for DVD using Apple Compressor Vers 3.5.2. This project calls for 2.0 Stereo as well as 5.1 surround. I am wondering if I should check or un-check the Low-Pass Filter for the Full Bandwidth Channels for the 2.0 stereo track.
    Same question for the 5.1...
    In case it's important to note, the LFE track of the 5.1 mix has low frequency effects only and nothing else.
    The explanation in the manual seems confusing to me. Would someone be kind enough to help me determine the correct setting?
    Thanks in advance!
    Xavier

    Hi David,
    Thanks for your reply. I think I'll just turn OFF this filter for both my 2.0 Stereo and 5.1 Surround tracks.
    In the name of proper communication however something still doesn't make sense. The compressor manual states the following:
    Full Bandwidth Channels
    Apply Low-Pass Filter: Select this checkbox to turn on a low-pass filter with a cutoff near the available audio bandwidth that is applied to the main input channels. If the digital signal fed to the main input channels does not contain information above the available audio bandwidth, you can turn off this filter. Compressor will automatically determine the available bandwidth.
    Question 1: What/which is the available audio bandwidth?
    Question 2: Why would anyone want to apply a Low-Pass filter to a FULL bandwidth channel? I would think that since these are FULL bandwidth channels you would want to maintain the full range of frequencies. No?

  • How can I stop my lock-in results from oscillating. The low pass filter is creating artificial noise

    I am using the lock in amplifier kit and sort of sending some of the parameters manually. I choose manually the low pass filter.
    Now I find strange behavior depending on the filter I choose. 
    The lock in results oscillates in time, the higher the dB roll off the longer it seems to take to stabilize. Also the frequency of the oscillations becomes lower. This I don't find too weird, the problem is that it just won't stop. 
    If I use a small time constant and there is no real change in my signal I can easily follow the shape of the the oscillations. 
    If I use a larte time constant it seems there is an average over the oscillation and then it looks as if it was noise. 
    All the time my signal has not changed one bit. 
    This is very anoying since it produces about 20-300microV of noise. (peak to peak amplitude of the oscillations) 
    So far I've gotten the best results with the IIR (5dig) with 40dB roll off and order 1
    Does anyone have an idea of what to do?

    Hi BlankaFlux,
    could you maybe provide us with a more specific example? What kinds of filters have you tried?
    For information on advanced digital filter use, please see the following pages:
    - Working with LabVIEW Filtering VIs and the LabVIEW Digital Filter Design Toolkit VIs
    - Digital Filter
    Maybe you could look into trying the NI LabVIEW Digital Filter Design Toolkit

  • Low pass filter (PXI 4472)

    Hi,
    I would like to know whether the PXI4472 module has a built-in low pass filter ?? If yes, can you send me the specfication for that filter?? Also, does the the SCXI 1125 support Vrms = 2500V isolation ??

    Hello,
    The PXI-4472 has a antialias filter which limits the bandwidth of the signal it can represent. The SCXI-1125 has +-300 Vrms of working isolation per channel. The information regarding the PXI-4472 filters and the SCXI isolation specifications may be found at NI Product Manuals.
    Let me know if you have any further questions. For direct questions regarding the PXI-4472, you will be better off posting a new question to the DSA discussion forum.

  • Low pass filter in LabVIEW Base Development System

    Hello,
    I've got a problem for several days and I haven't find even a hint to fix it so it's driving me crazy.
    I'm developing an application on LabVIEW Base Development System for automatical aquisition and exploitation of five signals.
    These signals are generated by a deformation gauge and four potentiometers linked to a NI USB 6210.
    I'm using the DAQ assistant on LabVIEW to get and use these signals.
    My problem is that I need a 2nd order low pass filter on the deformation gauge signal to get something I can use afterward and none is include in the Base development Sytem of LabVIEW.
    I'm sure there is a way to pass through this without buying the Full Development version but I haven't found it yet.
    Does anybody has already had this problem and succeed in fixing it ?
    If yes, can I have the code ?
    Thanks

    Thanks for your responses.
    I've tried to create a subVI using the transfer function of the filter I need.
    Here is the diagram of this subVI :
    I'm not sure of this transfer function at all. It seems too simple to me.
    Does it look weird to you or does a low-pass second order filter can have such a simple transfer function ?
    I've tried it and my signal is still unstable. I guess I'm doing something wrong, but as I'm not that good in electronics, I can't figure out what.
    Thanks again

  • Low Pass Filter

    I have a Ceton InfiniTV4. I contacted their support and was told I should look into getting a "Low Pass Filter."
    What does a "Low Pass Filter" actually accomplish with FiOS TV?
    I can't really find a clear answer on this and was wondering if they're just blowing smoke or if it will do anything for me?

    HERE'S HOW I FIXED THIS
    I have a Ceton Infinitv 4 and I was experiencing horizontal pixelation every few seconds on certain channels (Travel HD, Food Network HD, EPIX HD, etc.
    Everyone kept talking about this low-pass filter but I really didn't want to have to call Verizon and get a truck roll, etc . etc. I was surprised that I couldn't find a single Low Pass Filter on the internet that other Fios customers had tried and worked.  This is apparently the one that Ceton recomended in a message board buried on the internet (took me an hour to find it).

    I bought it, it worked, I'm happy. No more pixelation )

  • Scxi 1120 low pass filter specs for anti aliasing

    Hia,
    I'm am currently finnishing the development of a multi channel spectral analysis unit and I am concerned about aliasing. I have observed that the 1120 isolation amplifiers that I am using have a two position low pass filter for 4Hz and 10kHz now my problem is this, I'm sampling at 25600Hz and thus need to attenuate the signals by 12800, as i am using a 16bit AD card to be able to maximise its resolution I need to attenuate the signals to -92 dB  (or -96 dB  I can't remember which one) by this frequency.
    does anyone have details of the 1120's 10kHz filter? can I get away with using this or do I need to use a speciallist anti aliasing filter (which wouldn't be as tough a filter as I am only interested in signals up to 5kHz so I could have a much slower roll off)\
    Cheers
    Any help would be appreciated
    90% of all experts aggree that 1 out of 10 experts are wrong

    The specific characteristics of the SCXI-1120 are not available because the filter is not high-performance since it is designed speicifically for noise rejection. From the SCXI-1120 user's manual (http://www.ni.com/pdf/manuals/320425d.pdf), you can see that there are two lowpass filter stages, and then there is also a bandwidth limitation imposed by the amplifiers. The two filter stages are simple RC filters, so I would doubt that the roll-off is steep enough to reach -92dB attenuation at 12.8kHz. I would recommend either designing your own first stage filter, like you had mentioned, or find a way to increase your sample rate.

  • Design a 1st order Butterwort​h low pass filter

    Hey there... Really hope that u guys can guide me to solve these questions.. =)
    Design a first order Butterworth low pass filter with cut-off frequency
    fo = 20 kHz and the gain K = 1. You will need to simulate the circuit
    using Multisim and shows that the circuit meet the required
    specification.
    i)Show all calculations steps and assumption made in your circuit design.
    (DONE!)
    ii)Show the circuit schematic with all the resistor and capacitor values labelled.(attachment)
    iii)Perform frequency response analysis on the circuit and obtain the
    bode diagram. The bode diagram should show the voltage gain (Vout /
    Vin) in dB vs the signal frequency (0 to 100 MHz). Does the -3dB
    cut-off frequency match the desired cut-off frequency fo = 20 kHz ?
    Explain. From the graph, estimate the roll-off rate. (attachment)
    I inserted my schematics and graph.. am i right?

    Question 2a.zip ‏146 KB

    Just an update for the community, in version 11 and 12 of Multisim, there are some circuit wizards available which can make designing some basic circuits easier. To access the filter wizard, go to Tools -> Circuit Wizard -> Filter Wizard. You can put in the parameters and Multisim will automatically generate the filter for you.
    Hope this helps.

  • Bessel low pass filter and sampling frequency

    I have a 20 kHz sine wave signal, use the Bessel LowPass filter.
    The input parameters for the filter are as followings: sampling freq: 204800, Order: 8, low cutoff freq: 30000.
    The filtered X has a much lower amplitudue compared to to the input signal.
    If I change the sampling frequency to 80000, it seems the filtered X is better.
    Can you please explain the behavior of the filter?

    Thank you for the reply!
    I attached a test vi, which generates a sine wave and calculate its RMS (basic DC/RMS). The sine wave is then passed to a low pass filter, a new RMS is calculated from the filtered signal.
    Test case 1:
    Frequency = 10 kHz, Amplitude = 4, Sampling Info: Fs = 80 k, #s = 1000; Low pass cutoff frequency = 30 k; Filter sampling frequency = 80k.
    The signal RMS  = 2.8284; Filtered signal RMS = 2.71.
    Test case 2:
    Same setup as case 1, change the Filter sampling frequency to 204800.
    The signal RMS  = 2.8284; Filtered signal RMS = 2.4688.
    Test case 3:
    Frequency = 20 kHz, Amplitude = 4, Sampling Info: Fs = 80 k, #s = 8000; Low pass cutoff frequency = 30 k; Filter sampling frequency = 80k.
    The signal RMS  = 2.8284; Filtered signal RMS = 2.21.
    Test case 4:
    same setup as case 3, change the sampling frequency to 204800.
    The signal RMS  = 2.8284; Filtered signal RMS = 1.5369
    Can you please why increasing the sampling frequency will get lower RMS value?
    Thanks.

  • Sample Frequency of Low Pass filter VI is ambiguous

    I am having trouble understanding how the Sampling Frequency of the Low Pass Filter actually impacts the function buried within. The information passed in is an array with no relavance to time. How does the function actually sample this array of data at a frequency?

    I doubt that they actually build a waveform. Here is my guess: By defining a sample frequency they can get the sampling interval dt as you indicated.  By defining a sampling frequency the cutoff frequencies can be scaled to frequency units (Hz), making the VI easier to use.

  • Low pass filter of DAQ USB 6255

    Hi there
    I am using USB 6255 data acquisition board. The cutoff frequency of the internal low pass filter is 1.7 MHz, therefore, the background noise with frequencies below 1.7 MHz cannot be eliminated. The multiple channel signals I am measuring have 10 KHz frequency and the amplitude from 2 mV to 20 mV, but the accurate measurement cannot be achieved even I set the AI measurement range is 100 mV. Could you please guide me to add a extra analogue or digital low pass filter and keep the fast response time if possible? Thank you.

  • Low Pass Filter Counter Input Compact DAQ

    Hello,
    I need to put a 10kHz Low pass filter on a counter input.
    I have a CDAQ 9178
    and a 9421 Digital Input module
    Acording to the documentation and my own experience I can't enable the filter on the Digital input card.
    Is there another way to do this?  I need to filter the signal in hardware.
    Thanks
    Dan

    Your filter might work, however it is build to filter power lines, with current rating 6A and powerline voltage. You pay a lot for a box with screw terminals and a lot of copper and high rated capacitors.
    Have you tried a simple RC lowpass (costs less than 50 cent, even when purchased in a pharmacy ) ? R=1500Ohm, C=10nF gives a coarse 10kHz first order lowpass. The C fits between the ground and input terminals of your DAQ, the R in the signal line to the input.
    Output impedance of your source?
    If you explain more of your application, type of signal, we might find other solutions.
