Abstract
A time-multiplexed CCD transversal filter includes N filter sections each comprising N substantially identical CCD's connected in parallel. An N-phase clock is connected to each filter section to provide a sampling frequency f.sub.s which is N times the clock frequency f.sub.c. The output taps of all the devices in a filter section are weighted in a predetermined manner and summed, and the outputs of all the filter sections are multiplexed to provide a continuously valid output.
