Discussion on Demodulation Methods for Amplitude Modulation Wave

Jincun Zheng

Abstract

The demodulation effect in common circuit which use diode to detecte peak value and synchronous demodulation circuit was discussed, and a demodulation method for amplitude modulation wave is presenxed.The modulation signal is squared, filtered, extracted and filtered., and no local carrier wave involved.Finally EWB circuit and simulation result for each method are described in detail.
