superheterodyne receiver

(ˌsuːpəˈhɛtərəˌdaɪn)
n
(Telecommunications) 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
[C20: from super(sonic) + heterodyne]
ThesaurusAntonymsRelated WordsSynonymsLegend:
Noun1.superheterodyne receiver - a radio receiver that combines a locally generated frequency with the carrier frequency to produce a supersonic signal that is demodulated and amplified
heterodyne oscillator, local oscillator - an oscillator whose output heterodynes with the incoming radio signal to produce sum and difference tones
radio receiver, radio set, receiving set, tuner, radio, wireless - an electronic receiver that detects and demodulates and amplifies transmitted signals
