Abstract
A signal multiplier for multiplying first and second input signals each having time-varying amplitudes and relatively wide bandwidths in which a first input signal is added to at least one sinusoidal reference signal having an amplitude larger than that of the first input signal. The amplitude of the signal so produced is limited and the limited amplitude signal is multiplied by the second input signal to produce an unfiltered signal. The signal components thereof having undesired frequency spectra are then filtered to produce a signal proportional to the product of the first and second input signals.
