het·er·o·dyne

 (hĕt′ər-ə-dīn′)
adj.
Having alternating currents of two different frequencies that are combined to produce two new frequencies, the sum and difference of the original frequencies, either of which may be used in radio or television receivers by proper tuning or filtering.
tr.v. het·er·o·dyned, het·er·o·dyn·ing, het·er·o·dynes
To combine (a radio-frequency wave) with a locally generated wave of different frequency in order to produce a new frequency equal to the sum or difference of the two.

[hetero- + -dyne, power, frequency (from Greek dunamis, power; see dynamic).]

heterodyne

(ˈhɛtərəʊˌdaɪn)
vb
(Electronics) electronics to combine by intermodulation (two alternating signals, esp radio signals) to produce two signals having frequencies corresponding to the sum and the difference of the original frequencies. See also superheterodyne receiver
adj
(Electronics) produced by, operating by, or involved in heterodyning two signals

het•er•o•dyne

(ˈhɛt ər əˌdaɪn)

adj., v. -dyned, -dyn•ing. adj.
1. pertaining to a method of changing the frequency of an incoming radio signal by adding it to a signal generated within the receiver to produce fluctuations of a frequency equal to the difference between the two signals.
v.t.
2. to mix (a frequency) with a different frequency so as to achieve a heterodyne effect.
[1905–10; hetero- + -dyne < Greek dýnamis power]
