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.
A superheterodyne radio receiver.

(ˌsu pərˈhɛt ər əˌdaɪn)
1. noting or pertaining to a method of receiving radio signals in which the heterodyne process is used to lower the frequency of an incoming modulated wave and the wave is then amplified and demodulated.
2. a superheterodyne receiver.
