Abstract
A digital decimation filter which includes a multiplexer which receives signal values x.sub.i at a sampling rate of 1/T and where output signals which have half the sampling rate are supplied to two outputs. Separate bit associated circuits BP1 and BP2 are connected to the outputs for each significant figure of the p-place binary filter coefficients c6 through c1 and each of the bit associated circuits include partial products stages Mc6.sub.0 . . . Mc1.sub.0, Mc6.sub.1 . . . Mc1.sub.1 for all of the filter coefficient bits and the bit associated circuits also contain adder-register iterative circuits including delay elements and the output of the iterative circuit of the most significant bit plane BP2 is the output of the filter.
