superheterodyne receiver

基本解释

This paper first discusses the instinct disadvantage of a superheterodyne receiver, which is that it has more spurious response.
本文首先指出了超外差接收机的固有缺点，即它有更多的虚假响应。
In this paper, a superheterodyne receiver is taken as an example to illustrate the characteristic and effect of virtual experiment teaching.
并以超外差接收机的工作原理为例，说明了虚拟实验教学的特点和作用。
The system uses the emitter to send ultra high frequency signals after coding with signal coder and the secondary superheterodyne mixing receiver to accept the moving target signals.
系统中发射器采用编码器编码后发送超高频信号，接收器采用二次混频型超外差式接收移动目标信号。

a radio receiver that combines two radio-frequency signals by heterodyne action, to produce a signal above the audible frequency limit. This signal is amplified and demodulated to give the desired audio-frequency signal (Sometimes shortened to superhet)
