Abstract
Polyphased input data is filtered. A number of delay lines are provided corresponding to the number of polyphases. Each delay lines stores a set of input data samples. Filter elements are provided for each delay line. The filter elements operate at a particular time on different subsets of the input data samples stored in the delay line. During a given time interval a number of new input data samples corresponding to the number of filter elements in the group of filter elements are shifted into the delay line. During a plurality of subintervals within the time interval, groups of filter coefficients are supplied to the group of filter elements. In each subinterval, all of the filter elements within the group receive the same set of filter coefficients, and output an output data sample. Output data samples from corresponding filter elements for different delay line are combined to produce filtered data.
