Hi all,

I've FFT plot for a signal. I want to find the frequency ranges in which the peaks are coming.

For example, in this case, I've marked 6 frequency ranges.

How do I get that??? I really need your help as I'm new to Matlab and signal processing.

I'm attached sample time domain data also. [ts=.5*10^-6; Fs=1/ts;]

在 MATLAB Online 中打开

doc findpeaks

if you have the Signal Processing Toolbox. It has various parameters that you would have to play around with. How you are defining the regions around a peak I don't know though. You'll have to find a way to put that into a condition you can test for.
