I have a time domain data and also a FFT of this data. But when I use fwhm(x,y) then it says
Pulse Polarity = Positive
Pulse is Impulse or Rectangular with 2 edges
I am trying to also use findpeaks() but I don't know how to proceed after that. Any help would be appreciated. Thanks
Since the data is larger than 5 MB, I have attached the link to the data. Thanks,
There are 4 signals in the data and the first row is the frequency. I get the fwhm of only 2nd and 4th signals. Others show NaN. But the ones that I get are too incorrect as getting 4e3 and 4e7, which doesn't make sense. I have a nice FFT as attached below.
