- noun A superheterodyne radio receiver.

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.

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.
