Abstract

A method and apparatus for the transmission of time discrete signals between source and sink systems wherein a first signal x(n) is generated by the source system at a first sampling rate f.sub.i and a second time discrete signal y(m) is generated by a sink system at a second sampling rate f.sub.0. The method is carried out by cyclically distributing the first time discrete signal to each of L filter groups at the first sampling rate f.sub.i. Each of the L filter groups comprises M filter elements which have their inputs connected to a common terminal and have the transfer function H.sub.l,m (z.sup.LM, where L and M are integers, l is an integer 0, 1 . . . L-1 corresponding to the filter group in which the filter element is located and m is an integer 0, 1 . . . M-1 corresponding to the location of the filter element in its associated filter group. The first time discrete signal is filtered in each of the filter elements at a processing rate f.sub.i /L and the filtered signals stored in the filter elements. Thereafter, the stored outputs of the M filter elements in each of the L filter groups are cyclically sampled at the second sampling rate f.sub.0 and coupled to corresponding inputs of a summing element which generates a signal f.sub.0 at its output equal to M/L f.sub.i.
