ABSTRACT:
A signal processing arrangement which discriminates against large-amplitude nterference signals and in favor of information signals. Incoming signals are separated into a plurality of contiguous frequency channels whose total frequency coverage is the frequency band of interest. The signals in the individual channels are then amplitude limited so that relatively narrow band interference signals are limited while a wide band desired signal is not. The desired signal is then spectrally compressed to obtain a high amplitude signal while the remaining interference signals are spread and rejected.
