I'm trying to calculate a spectrogram where the frequencies are logarithmicaly spaced, instead of the usual linear. I think my test script follows the documentation, but my two spectrograms are identical and are both clearly using linear frequency spacing. uniweld nv1 nitrovue nitrogen flow indicator
Determine frequency from signal data in MATLAB - Stack Overflow
WebIf your measurement is done in the pass-band (2.38 GHz-2.46 GHz), so the maximum frequency is 2.46 GHz which means that the sampling frequency should be at least 2x2.46 GHz = 4.92 GHz. WebGreetings, I'd like to plot the amplitude ratio and phase differences of two signals. I used the following code to calculate and plot the amplitude ratio and phase differences by modifying the c... WebMar 6, 2024 · Ts = mean (diff (t)); where ‘t’ is the time vector, assuming the sampling interval is regular. I use the standard deviation of diff (t) as: St = std (diff (t)); as a measure of the regularity of the sampling intervals.
