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)
