ABSTRACT:
A semiconductor filtering apparatus substantially fabricated as a metal-oxide-semiconductor (MOS) integrated circuit that permits discrete time correlation or convolution of an analog input signal with a binary or analog correlating signal. The apparatus may also be employed as a recursive filter. A plurality of novel bucket-brigade charge transfer means are employed to shift the input analog signal past non-destructive read-out taps. Electrically programmable floating gate devices are used to store either a binary or analog correlating signal. The sum or difference signal associated with each of the plurality of charge transfer means is weighted to produce the final filter output in one embodiment.
