ABSTRACT:
A multiplier circuit for obtaining the product of two input signals has a modulator for modulating a first input signal to produce an intermediate pulse train whose pulse density is dependent on the amplitude of the first input signal. A combiner derives from the second input signal and the intermediate pulse train a composite signal whose average value is equal to the product of the first and second input signals.
