Abstract
A pattern recognition system includes a filter bank, coupled via rectifying elements to integrators which are coupled via different weighting elements to the summing nodes of a summing amplifier. The filter bank, integrators, and weighting elements include switched capacitors enabling the manufacture of the filters, rectifiers, integrators and weighting elements on a monolithic integrated circuit chip. The frequencies at which the capacitors are switched are programmable enabling the system to be easily 'retuned'.
