"WebDownsampling — Signal Phases This example shows how to use downsample to obtain the phases of a signal. Downsampling a signal by M can produce M unique phases. For example, if you have a discrete-time signal, x, with x (0) x (1) x (2) x (3), ..., the M phases of x are x ( nM + k) with k = 0,1, ..., M -1. " - Downsampling example
