Overview
Block statistics of a block of samples
Discussion
This module calculates the Block Statistics of the input signal on a block-by-block basis. The input pin can have an arbitray number of interleaved channels and the Block Statistics calculation occurs over all channels. The output pin has a single channel and a blockSize of 1.
...
The module also exposes computed signal as state variable; instantaneousValue holds the Block Statistics of the block.
