Abstract:
A filter, comprising:an input port; m parallel input paths coupled to receive an input signal from the input port, each of the parallel input paths including a plurality of output taps with each of the output taps representing a sample value of the input signal at a particular point in time as determined by a sample period of the filter, the m parallel input paths being arranged so that successive samples of the input signal within each input path are separated from one another by m sample periods with a first sample in each of the m parallel input paths being shifted from a predecessor one of the input paths by one sample period; and m output paths, each coupled to receive a subset of the output taps of the m input paths such that successive samples are received from successive ones of the input paths in a round-robin fashion and to produce an output signal that is a summation of products of selected ones of the output taps with weight coefficients.
