Overview
Computes sample statistics over multichannel signals
Discussion
This module calculates the sample statistics of the input signal on a sample-by-sample basis. The input pin can have an arbitray number of interleaved channels and the sample statistics calculation occurs over all channels. The output pin has only a single channel and a blockSize equal to that of input.
...
The module also exposes the computed signal as a state variable.
