Abstract
A phase multiplexed CCD transversal filter includes N substantially identical parallel-connected CCD's which acquire samples in a predetermined consecutive order over a given clock cycle so that the apparent sampling frequency is equal to N times the clock frequency. The output taps of the CCD's are weighted in a predetermined manner to provide a filter having a predetermined transfer function.
