  • 超外差接收机学习（Superheterodyne Receiver） - 知乎
    要理解“超外差（Superheterodyne）”，我们需要把它拆开来看： 外差（Heterodyne） 和 超（Super）。 “外差”这个词源于希腊语： Hetero- 意思是“不同的（different）”。 -dyne 意思是“力量 功率（power force）”。 在无线电术语中，“外差”指的是 将两个不同的频率混合（相乘），从而产生新的频率（和频与差频）的过程。 在早期的无线电接收机中（主要是用来接收莫尔斯电报的等幅波 CW），工程师们就利用了“外差”原理：他们用一个本地振荡器产生一个频率，与天线接收到的射频（RF）信号混频。
