An Analysis of the Oscillating Limiter

Abstract

It is shown that where the output signal-to-noise ratio is required to be large, the oscillating limiter does not contribute any more signal-to-noise ratio enhancement than the limiter without feedback under the usual assumptions of Gaussian noise and a quasi-sinusoidal signal. However, it is possible that variation of the signal amplitude with frequency and/or nonlinear phase characteristic in the feedback loop of the oscillating limiter may result in an improvement in signal-to-noise ratio over that of a simple limiter.
