Wikipedia
Heterodyning is a radio signal processing technique invented in 1901 by Canadian inventor-engineer Reginald Fessenden, in which new frequencies are created by combining or mixing two frequencies. Heterodyning is used to shift one frequency range into another, new one, and is also involved in the processes of modulation and demodulation. The two frequencies are combined in a nonlinear signal-processing device such as a vacuum tube, transistor, or diode, usually called a mixer. In the most common application, two signals at frequencies and are mixed, creating two new signals, one at the sum of the two frequencies, and the other at the difference . These new frequencies are called heterodynes. Typically only one of the new frequencies is desired, and the other signal is filtered out of the output of the mixer. Heterodynes are related to the phenomenon of " beats" in acoustics.
A major application of the heterodyne process is in the superheterodyne radio receiver circuit, which is used in virtually all modern radio receivers.
In poetry, a heterodyne is a word in which the syllable receiving stress and/or pitch change is other than the syllable of longer quantity. This misalignment is considered by most people to be phonetically challenging to recite, and when applied sporadically to several words in succession, it usually attracts the listener's attention to a higher degree than the more natural-sounding blend of meter and stress/pitch.
Only languages with a separate quantitative element can make substantial use of heterodynes, and people primarily refer to the poetry of classical languages when evoking the term.
