Abstract:
A digital filter (1) has a filter cell (4a) for generating processed data. The digital filter cell includes plurality of coefficient registers (14) which are arranged to circulate a plurality of coefficient values that correspond to a plurality of coefficients such that each of the plurality of coefficients is output once during a predetermined period. One or more data registers (11) are arranged to circulate a data value for a time which is at least as long as the predetermined period such that the data value is output each time that a different one of the plurality of coefficients is output.
