1. heterodyne - Noun
2. heterodyne - Adjective
3. heterodyne - Verb
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
of or relating to the beat produced by heterodyning two oscillations
Source: WordNetArmstrong (and others) eventually deduced that this was caused by a "supersonic heterodyne" between the station's carrier frequency and the regenerative receiver's oscillation frequency. Source: Internet
However, any nonlinear electronic component will also multiply signals applied to it, producing heterodyne frequencies in its output, so a variety of nonlinear components are used as mixers. Source: Internet
A major application of the heterodyne process is in the superheterodyne radio receiver circuit, which is used in virtually all modern radio receivers. Source: Internet
History In 1901, Reginald Fessenden demonstrated a direct-conversion heterodyne receiver or beat receiver as a method of making continuous wave radiotelegraphy signals audible. Source: Internet
However, optical heterodyne detection is possible and has been actively studied since 1979. Source: Internet
If the two signals are close together in frequency the heterodyne is low enough to be measured by a frequency counter. Source: Internet
