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

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?

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 Bradz

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 Bradz

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.......

Hey there, What i meant was to plot Frequency in the Y-axis against Real time in the X-axis. instead of the normal Amplitude vs Frequency for the frequency graphs, it is shown in Real time any idea?

Hey guys out there i need help >< i want to plot frequency against time domain but what i can only get is the individual time and frequency plots. how do i plot them? its in Real time by the way. All help will be much appretiated
