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機的固有缺點，即它有更多的虛假響應。
In this paper, a superheterodyne receiver is taken as an example to illustrate the characteristic and effect of virtual experiment teaching.
竝以超外差接收機的工作原理爲例，說明了虛擬實騐教學的特點和作用。
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.
系統中發射器採用編碼器編碼後發送超高頻信號，接收器採用二次混頻型超外差式接收移動目標信號。

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)
