I have a signal of 15 seconds with a sampling rate of 20KHz. I need a table with the location of the 3 highest peaks of the FFT, every 0.2 seconds.
I was planning to use the retime along iwht the findpeaks and fft command but retime only gives me one output and no multiple outputs.
I know this is basically what a short time fast fourier transform does but I am looking for other alternatives that allow me to see and extract changes in the FFT over time, as a table and not as a image.
If any one have a solution, suggestion or an alternative please let me know.
