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.

v. 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.

adj. Of, two oscillations, having two slightly different frequencies such that, when combined, they produce a beat

n. The beat so produced

n. Either the sum or difference of the two oscillations

v. To produce heterodyne interference in a radio

v. To change the frequency of a signal by such a process

adj. of or relating to the beat produced by heterodyning two oscillations

v. combine (a radio frequency wave) with a locally generated wave of a different frequency so as to produce a new frequency equal to the sum or the difference between the two

"An energy center is at work in the tube, and its radiations are projected along a carrier beam that is of ultra-violet frequency and so adjusted as to heterodyne the Destinn wave."
