I need to calculate time-evolving power spectral density using Matlab periodogram function based on Welch theory to estimate the PSD of a moving boxcar filter with an overlap of 85%. In all the figures, values have to be plotted at the center of each window over which they are calculated.
I need to show the amplitude variations of signal at specific frequency.
