heterodyne

v. produce heterodyne; combine radio-frequency waves; cause interference

n. detection technique used widely in radio which involves combining the measured wave with a wave of different frequency to produce frequencies equal to the amount of and the difference between the two original signals; interference (in particular whistle)

adj. consisting of or produced by combined radio waves

In telecommunications, physics, and radio astronomy, heterodyning is the generation of new frequencies by mixing two or more signals in a nonlinear device such as a vacuum tube, transistor, diode mixer, Josephson junction, or bolometer. The mixing of each two frequencies results in the creation of two new frequencies, one at the sum of the two frequencies mixed, and the other at their difference. A heterodyne receiver is a telecommunication receiver which uses this effect to produce frequency shifts.
