WEIGHTEDAVERAGEFILTER - Compute the weighted or self-weighted average

Usage

outsig = weightedaveragefilter(insig,weight,fs,timeconst)

Input parameters

`insig`	signal from which the average is computed. Optionally, can be the same as the weight resulting in self-weighted average
`weight`	signal to be used as weight in the computation
`fs`	sampling rate
`timeconst`	time constant specifying the first-order IIR filter

Output parameters

outsig

output signal

Description

This function computes the either the weighted or the self-weighted average of the input signal using a first-order IIR filter whose time constant is specified by the timeconst argument. More details about the conputation can be found in Pulkki, Hirvonen 2009 (Sec. 3.2.3)
