ABSTRACT:
A digital filter for shared-time processing on several channels. The filter has several elementary cells (C.sub.1 to C.sub.K), each comprising a read-write memory (M.sub.1 to M.sub.K), a read-only memory (H.sub.1 to H.sub.K), and an arithmetic unit (U.sub.1 to U.sub.K). A page address counter CT.sub.1, a word address counter CT.sub.2 and a weighting coefficient address counter CT.sub.3 are common to the cells. Delayed discrete values are transferred by the relative addressing of the memory words. The filter will find particular application as a half-band extrapolator filter for telephone switching.
