Overview
Downsampler (or decimator) - keeps 1 out of every D samples
Discussion
Multichannel downsampling module. When downsampling by a factor of D, the module will keep 1 of every D samples, with the other samples being discarded. No filtering is incorporated within the module. It is expected that the user will incorporate the filters of their choice to systems that incorporate downsampling.
