# Calculate PSD of a signal using Welch algorithm 1.0

Date Added: June 23, 2013  |  Visits: 251

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.Original Author(s): T.
