ABSTRACT:
An analog signal processor in which the voltage is sensed across a plurality of charge storage elements to derive an output signal. With this arrangement, the effects of signal interaction encountered in charge sensing are eliminated. The processor can be readily implemented using MOS (metal-oxide-silicon) technology whereby the charge is manipulated by electronic data and stored at the surface of the semiconductor substrate. It is particularly adapted for use as a programmable cross-correlator or a transversal filter.
