Bradz Posted March 31, 2005 Report Share Posted March 31, 2005 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 Quote Link to comment
todd Posted March 31, 2005 Report Share Posted March 31, 2005 Is this called a moving FFT? Perhaps the waterfall in this toolkit is along those lines. Quote Link to comment
Bradz Posted March 31, 2005 Author Report Share Posted March 31, 2005 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 Quote Link to comment
Bradz Posted March 31, 2005 Author Report Share Posted March 31, 2005 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? Quote Link to comment
