superheterodyne receiver

基本解釋

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(jī)的固有缺點，即它有更多的虛假響應(yīng)。
In this paper, a superheterodyne receiver is taken as an example to illustrate the characteristic and effect of virtual experiment teaching.
并以超外差接收機(jī)的工作原理為例，說明了虛擬實驗教學(xué)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(tǒng)中發(fā)射器采用編碼器編碼后發(fā)送超高頻信號，接收器采用二次混頻型超外差式接收移動目標(biāo)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)
