Definitions and meanings of "Heterodyne"

What do we mean by heterodyne?

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. adjective

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. transitive verb

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

The beat so produced noun

Either the sum or difference of the two oscillations noun

To produce heterodyne interference in a radio verb

To change the frequency of a signal by such a process verb

Of or relating to the beat produced by heterodyning two oscillations adjective

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 verb

The beat so produced

Either the sum or difference of the two oscillations

Is a signal processing technique invented in 1901 by Canadian inventor-engineer Reginald Fessenden that creates new frequencies 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 f1 and f2 are mixed, creating two new signals, one at the sum f1 + f2 of the two frequencies, and the other at the difference f1 − f2. 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 the mathematical dual of 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. Urban Dictionary

The word "heterodyne" in example sentences

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. ❋ Johnny Pez (2010)

Infrared heterodyne spectroscopy, such as that provided by the Heterodyne Instrument for Planetary Wind and Composition (HIPWAC), provides the only direct access to ozone on Mars with ground-based telescopes; the very high spectral resolving power (greater than 1 million) allows Martian ozone spectral features to be resolved when they are Doppler shifted away from ozone lines of terrestrial origin. ❋ Unknown (2010)

Already in 1924, the Times made a technological leap by investing in a super-heterodyne receiver, which allowed it to receive direct transmissions of reports from Europe and positioned the Times as the best place in the US to get news about the rest of the world. ❋ Unknown (2009)

He was a young radio pioneer, and when Sarnoff and Armstrong were both very young men, Armstrong invented something called the -- called the feedback circuit, the heterodyne circuit, which allowed radio signals to be broadcast and received over greater distances than ever before. ❋ Unknown (2002)

The thyristor ignition set is an electronic heterodyne ignition set and consists of various semiconductor elements as well as of a pulse transformer. ❋ Frank Ponemunski (1991)

A screen worn on the head will heterodyne the outgoing radiation in a random fashion, make it absolutely undecipherable. ❋ Anderson, Poul, 1926- (1974)

Your own electrodynamic characteristics have been analyzed; I am sorry to say that it will now be necessary to heterodyne your normal senses. ' ❋ Heinlein, Robert A. (1967)

Appalling sounds come from one end of each-in which they heterodyne each other-and even more appalling conditions prevail at the other ends. ❋ Heinlein, Robert A. (1963)

It wasn't friction that made the squeal, but a heterodyne of vibrations from the generators that drove the car. ❋ Pohl, Frederik & Williamson, Jack (1963)

There had been time for the reply, but still that maddening heterodyne whistle came unbroken from the speaker. ❋ Clarke, Arthur C. (1951)

The heterodyne stopped and Helen Curtis was still sobbing at the microphone three hundred miles away, beneath the coloured picture of the King and Queen in coronation robes and the picture of their daughter's wedding group that stood upon the set. ❋ Shute, Nevil, 1899-1960 (1950)

She went back to her chair, and now a heterodyne squeal shrilled out, drowning the sobbing as some sympathetic, foolish woman came in on the same wave saying something unintelligible. ❋ Shute, Nevil, 1899-1960 (1950)

If we try to heterodyne his radio -- presto -- it has twice the heat energy anyway, though we might reduce it to a frequency that penetrated the ship instead of all staying in it. ❋ John Wood Campbell (1940)

"In this case, a heterodyne frequency of a lower, and harmless frequency." ❋ John Wood Campbell (1940)

I should have known that with all the light frequencies in heterodyne for visibility, enough of that same stuff would leak through to make strong medicine on these visiplates -- for I knew that that bar weighed a hundred tons and would liberate energy enough to volatilize our Earth and blow the by-products clear to ❋ Hans Waldemar Wessolowski (1927)

He can penetrate the impenetrable shield of force and can operate mechanisms of pure force behind it; he can heterodyne, transmit, and use the infra-rays, of whose very existence we were in doubt until recently! ❋ Hans Waldemar Wessolowski (1927)

With two fields of force, set up from data 27 to 43, it will be possible actually to project a pure force of such a nature that it will react to de-heterodyne the blanketing frequency at any predetermined distance. ❋ Unknown (1927)

I [thought] heterodyne meant the [oral copulation] of a [heterosexual]. ❋ Yyuryyubicuryy4me (2018)
