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]
