Abstract
A sub-band filter system in which the frequency separated data is multiplexed together at the output of each filter stage. The stream of multiplexed data produced can have a block-by-block format or a sample-by-sample format. In the latter case, the filtering can be effected by a finite impulse response filter with switchable tap coefficients for effecting both decimation and high and low pass filtering.
