Investigation of a detector of digital amplitude-modulated signals

Yu. A. Bryukhanov

Abstract


The paper considers operation of an amplitude detector of digital signals, where the detector contains a nonlinear element (a full-wave digital gate) connected in series with a digital filter. Dependencies of the detection coefficient of the harmonic distortion factor on the digital filter parameters are established. The results are compared with the case when a half-wave digital gate is used.
