FFT in Matlab and computation of mean frequency
7 views (last 30 days)
I've a .mat file within a signal sampled at 1000Hz. I need an algorithm that visualizes the spectrum and returns mean frequency.
The mean frequency is this: http://luscinia.sourceforge.net/page26/page35/page35.html
I tried to do the fft but I don't understand how to continue and get components amplitude and their frequency for mean frequency computation.
