| 摘 要： | 常规双边带调幅（AM）信号的特点是载波的振幅受调制信号的控制作周期性的变化,变化的周期与调制信号的周期相同,振幅变化与调制信号的振幅成正比。常规双边带调幅波（AM）信号的解调是把接收到的已调信号还原为调制信号。它的解调方法有两种：相干解调与包络解波。本文对常规双边带调幅波（AM）信号的原理、具体实现电路、解调的的原理、解调的具体实现电路进行了研究和分析。

| Abstract: | The AM is the signal that amplitude of the carrier is controlled by modulation signal and the cycle time and the modulation signal cycle is the same, the oscillation amplitude change and modulation signal＇s oscillation amplitude is proportional. The AM signal demodulation was receives has moved the signal to return to original state into the modulation signal. The demodulation has two Methods： Coherent Method and Incoherent Method. This article to the conventional the AM signal principle, realizes the circuit, the demodulation specifically the principle, the demodulation circuit to conduct the research and the analysis specifically. |
