  1. Hey guys

    Need a little help with the filtering. As the filter block range values are in hertz, is it possible to do filtering of a original signal in time domain?

    I am only able to do it after the Spectral Measurement block which i am not sure if it is correct. Please Advice :)

  2. hi there

    i believe my labview does not have the sound and vibration toolset which includes the feature waterfall.

    i used the Spectral Measurements block to generate and display the FFT of a signal. Is there any possible way to input FFT results into the y-axis against real time? maybe using the Build XP graph?

  3. hey todd

    thanks for the help. yea that is what i am looking for. a moving FFT i suppose. But as i am relative new in Labview, i do now know how to access the toolkits in order for me to work with waterfall. Could u further explain in this section. Thanks

  4. Hey guys

    any idea how do i plot FFT(y-axis) against time(x-axis), the only plots i could get was FFT in frequency domain. But i want it against time instead. Probably have to change the axis? Not too sure how to go about it. Anyone? Thanks people

  5. hi guys

    Yea i need frequency against time for data analysis. How do i make it work if i am working with real time with everchanging values. i cant just simply put in fixed values in this situation. I can plot a normal signal in both time and frequency but how do i plot frequency against time.......
