het·er·o·dyne

 (hĕt′ər-ə-dīn′)
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.
tr.v. het·er·o·dyned, het·er·o·dyn·ing, het·er·o·dynes
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.

[hetero- + -dyne, power, frequency (from Greek dunamis, power; see dynamic).]

heterodyne

(ˈhɛtərəʊˌdaɪn)
vb
(Electronics) electronics to combine by intermodulation (two alternating signals, esp radio signals) to produce two signals having frequencies corresponding to the sum and the difference of the original frequencies. See also superheterodyne receiver
adj
(Electronics) produced by, operating by, or involved in heterodyning two signals

het•er•o•dyne

(ˈhɛt ər əˌdaɪn)

adj., v. -dyned, -dyn•ing. adj.
1. pertaining to a method of changing the frequency of an incoming radio signal by adding it to a signal generated within the receiver to produce fluctuations of a frequency equal to the difference between the two signals.
v.t.
2. to mix (a frequency) with a different frequency so as to achieve a heterodyne effect.

L-K11), with the expectation that measurements in the pilot and node laboratories be performed by a femtosecond-frequency comb, while measurements in host laboratories may be carried out in either of these ways: as the direct heterodyne measurements between two lasers at the same component (using an acousto-optic modulator for shifting the frequency of one laser, so that the frequency difference can be directly measured), or as matrix heterodyne measurements between two lasers on different components (thus the uncertainty is calculated from several measurements for pairs amongst d, e, f, g components).
