- adj. Of, relating to, or being a form of radio reception in which the frequency of an incoming radio signal is mixed with a locally generated signal and converted to an intermediate frequency in order to facilitate amplification and the rejection of unwanted signals.
- n. A superheterodyne radio receiver.
- From super- + heterodyne. (Wiktionary)
- super(sonic) + heterodyne. (American Heritage® Dictionary of the English Language, Fourth Edition)
“This is a four-valve seven-stage superheterodyne receiver essentially designed for C.W. reception.”
“Here were the somatic messages that fed the cauldron; cell reactions by the incredible billion, organic cries, the muted drone of muscletone, sensory sub-currents, blood-flow, the wavering superheterodyne of blood pH ... all whirling and churning in the balancing pattern that formed the girl's psyche.”

“Grey-cast, billiard-bald Major Edwin Howard Armstrong, deviser of the frequency modulation system of broadcasting, has twice in his time revolutionized radio-first by the regenerative, or feedback, circuit, which outmoded crystal sets; next by his superheterodyne hookup, the basis for present-day one-dial tuning.”
“Range in high altitude (more than 100m): RC approx. 1,5km (cheap RC receiver, no DS = double superheterodyne) FPV approx. 3km Half the range in big cities because of jammers!”
“QST would have run its first articles on the superheterodyne receiver and crystal controlled oscillators.”
“For frequencies above 40MHz, the actual ADCs doesn't perform sufficient speed so direct-conversion is not possible and hence a superheterodyne RF front end architecture is adopted, to lower the frequency of the received signals to intermediate frequency values (IF) under the actual 40MHz convertible limit.”
“Analog modulation systems-amplitude and angle modulation and demodulation systems, spectral analysis of these operations, superheterodyne receivers, elements of hardwares realizations of analog communications systems.”
