Description
The Moving RMS block computes the moving root mean square (RMS) of the input signal along each channel independently over time. The block uses either the sliding window method or the exponential weighting method to compute the moving RMS. In the sliding window method, a window of specified length moves over the data sample by sample, and the block computes the RMS over the data in the window. In the exponential weighting method, the block squares the data samples, multiplies them with a set of weighting factors, and sums the weighed data. The block then computes the RMS by taking the square root of the sum. For more details on these methods, see Algorithms.
