AM信号的过调幅实现及解调
Implementation of Overmodulation and Demodulation of AM Signal
【摘要】 在原理与技术上分析并实现了过调幅AM信号及解调,讨论了调幅系数ma不能大于1的原因。通过实验电路,得到了预想结果。
【Abstract】 Based on the theory and the technique of circuit,this paper analyzes overmodulation and demodulation of AM signal,and discusses the reason why the magnitude of the AM signal ma can not be greater than 1. Ex- pected result is obtained by means of the experimental circuit.
