超外差电路超外差电路superheterodynecircuit利用本地产生的振荡波与输入信号混频，将输入信号频率变换为某个预定的频率的电路。超外差原理最早是由E.H.阿姆斯特朗于1918年提出的。这种方法是为了适应远程通信对高频率、弱信号接收的需要，在外差原理的基础上发展而来的。外差方法是将输入信号频率变换为音频，而阿姆斯特朗提出的方法是将输入信号变换为超音频，所以称之为超外差。超外差电路的典型应用是超外差接收机，其优点是：①容易得到足够大而且比较稳定的放大量。②具有较高的选择性和较好的频率特性。③容易调整。缺点是电路比较复杂，同时也存在着一些特殊的干扰，如像频干扰、组合频率干扰和中频干扰等。随着集成电路技术的发展，超外差接收机已经可以单片集成。
