ABSTRACT:
Reduction of interference from off-frequency signals in an a.m. receiver is achieved by substituting an average detector for the conventional peak detector employed in such receivers. Conversely, enhancement of off-frequency signal reception is achieved by employing an average detector in parallel with a peak detector with their outputs subtracted.
