Given the following signal I would like to calculate the rate of damping.
I presume that I need to find out where the peaks are using some kind of smoothing on the sample data. After performing an FFT I get the following…
I guess I could perform some kind of clipping (high/low pass) and then do an inverse FFT to get the smoothed result.
Am I on the right track here? Are there some standard methods for achieving my goal?
