Day 3: Power Spectral Density Overview

Power spectral density calculated using PMTM

The same signal, but this time the power spectral density is calculated using pwelch

In our last post we introduced the two main characters in this story of spectrogram. On one end we have Welch’s method (pwelch) on the other end we have the Thomson multitaper method (pmtm). As promised here is a awful basic breakdown of why is more than one way to compute power spectral density (in fact there are several, far more than the two I’m talking about). So, let’s just dig right in!*
