THE EFFECT OF A REGENERATIVE LIMITER ON THE RANDOM-NOISE THRESHOLD IN FM SYSTEMS
Abstract
Research concerns the suppression of the randomnoise threshold effect in FM systems by applying strong regenerative feedback around the amplitude limiter. Little or no threshold suppression is predicted. This conclusion is reached analytically by retaining a nonzero correlation coefficient between the IF and the feedback noise throughout and by introducing a functional expression to take into account the effect of regenerative feedback on results derived by Davenport. A simple conceptual argument is also presented in support of the analytical findings, and some practical aspects of regenerative limiter implementation are considered. (Author)
