Spectral spread

Description

Given an FFT chain, this measures the spectral spread, which is the magnitude-weighted variance. This measure can serve as an (approximate) clue towards the bandwidth of a signal (although the value is not a frequency).

The centroid should be supplied, typically using a SpecCentroid unit - if you don't fill in this argument then a SpecCentroid unit will automatically be added.
