WebIn this example you learned how to perform frequency-domain analysis of a signal using the fft, ifft, periodogram, pwelch, and bandpower functions. You understood the complex nature of the FFT and what is the information contained in the magnitude and the phase of the frequency spectrum. You saw the advantages of using frequency domain data ...
