I have an electric signal that I need to analyze. If I do a
spectrogram of the data I get a good picture of what I want to see
(a
blurry section on a otherwise pure tone line). I need to detect
these blurry sections automatically. Is there any way to analyze a
spectrogram window by window to detect something like this? Could
I
do this with fft somehow? Any help or similar files would be
great!
Thanks!!
