Abstract

The paper considers operation of an amplitude detector of digital signals, where the detector contains a nonlinear element connected in series with a digital filter. For nonlinear element a full-wave digital gate is used. Dependencies of the detection coefficient and 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.
