carrier wave

noun

1. radio a wave of fixed amplitude and frequency that is modulated in amplitude, frequency, or phase in order to carry a signal in radio transmission, etc See amplitude modulation frequency modulation

Example Sentences

The researchers couple their resonating circuit to a second, higher frequency circuit, so that, much as in AM radio, any dark matter signal would make the amplitude of the higher frequency carrier wave warble.

From Science Magazine

The researchers modify their carrier wave by injecting a tiny warble at the frequency they hope to probe.

From Science Magazine

A dull carrier wave signal for instance.

From Scientific American

But for all those predispositions and plans the story could just as easily happen like this: a rumor, a leaked bit of news, a preliminary discussion from the scientists, and then lo-and-behold it’s basically all over, and the fact of a populated galaxy just becomes another piece of history: All because of a monotone carrier wave signal from Proxima Centauri emanating from some ordinary alien activity.

From Scientific American

Lightwave electronics3—the foundation of attosecond science4—uses the oscillating carrier wave of intense light pulses to control the translational motion of the electron’s charge faster than a single cycle of light5,6,7,8,9,10,11,12,13,14,15.
