demodulator AM using envelope detector

一些关于morlet wavelet的文章，分别是用Morlet小波进行包络检波分析，基于小波分析的进化谱及在故障诊断中的应用-Morlet wavelet is Morlet wavelet analysis of the envelope detector, based on the wavelet analysis of the evolutionary spectrum and its application in fault diagnosis

This m-file simulates the operation of the heterodyne section and demodulating section of a garden variety AM receiver. An array is created that represents the superposition of three separate RF carriers, each modulated at a different audio
