Investigation and Analysis of "Capture Effect" in F-M and A-M Communication Systems

Abstract

"Capture effect" is a phenomenon occurring in both a-m and f-m communication systems manifest in the depression of a relatively weak desired signal by a stronger interfering signal at or near the desired-signal frequency, the degree of depressing depending on circuit design, absolute and relative input amplitudes of the two signals, and on their frequency location relative input amplitudes of the two signals, and on their frequency location relative to predetector selectivity.
