This module calculates the Block Statistics of the input signal on a block-by-block basis. The input pin can have an arbitray arbitrary 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 following algorithm is used internally. For each block, caluclates the maximum minimum, maximum absolute value, mean, RMS, standard deviation, variance, average energy is computed depending on the variable statisticsType selection. This includes all channels and the entire block.
statisticsType | Description |
|---|---|
0 | maximum |
1 | minimum |
2 | maximum absolute value |
3 | mean |
4 | RMS |
5 | standard deviation |
6 | variance |
7 | average energy |
8 | sum |
9 | sum of squares |
The module also exposes computed signal as state variable; instantaneousValue holds the Block Statistics of the block.
