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(diǎn)，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.
竝以超外差接收機(jī)的工作原理爲(wèi)例，說(shuō)明了虛擬實(shí)騐教學(xué)的特點(diǎn)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)射器採(cǎi)用編碼器編碼後發(fā)送超高頻信號(hào)，接收器採(cǎi)用二次混頻型超外差式接收移動(dòng)目標(biāo)信號(hào)。

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)
