A simplified analysis is presented to explain physically the change of signal-to-interference ratio which occurs in a bandpass limiter. The analysis utilizes the concept of sideband resolution into symmetric and anti-symmetric parts and considers only the asymptotic case where the signal-to-interference ratio is small in comparison with unity. Wide-band correlation-detection systems are discussed, as well as ordinary band-pass systems. The important conclusion is reached that the degradation is… CONTINUE READING
