Calculate PSD of a signal using Welch algorithm
This function Calculates Power Spectral Density of signal vector X using Welch's averaged periodogram method.
X is divided into sections, then windowed by the WINDOW parameter.
The magnitude squared of the length NFFT DFTs of the sections are averaged to form Pxx. Pxx is length NFFT/2+1 for NFFT even. the default fot WINDOW is a rectangular window .
Fs is the sampling frequency which is used for scaling of plots.
