摘要
输出电压直接反映高频调幅包络变化规律的检波电路称为包络检波电路,它只适用于普通调幅波的检波。本文采用二极管和低通滤波器串联组成的二极管包络检波电路对调幅波进行检波并得到原调制信号,从而实现振幅调制信号的解调。
Output voltage is directly reflect the variation of amplitude envelope detection circuit of high- frequency called envelope detection circuit, it is only suitable for the ordinary amplitude modulation wave detection. This paper adopts the diode V and RC low pass filter is composed of diode envelope detection circuit on the wave amplitude demodulation and get the original modulation signal, so as to realize the demodulation of amplitude modulation signal, wherein the negative peak and caused by the distortion of envelope detection circuit inert cutting distortion in-depth study~
