A high-frequency electromagnetic wave modulated in amplitude or frequency to convey a signal.

Example sentencesExamples
So far we have cataloged over two hundred separate signals carrying some sort of data and nearly as many empty carrier waves with more being cataloged as the planet comes farther from eclipse behind the sun.
The carrier wave broadcast from a radio tower is very weak by the time it reaches your set, but it is essentially electrical power.
This signal was then used to ‘modulate ‘a radio wave called a carrier wave - the wave that actually transmits the signal.’
The transmitter mixes the signal with some strong radio signals called carrier waves.
This concept is frightening to most radio frequency engineers as it denies the need for a carrier wave.
You tune into a certain station with your dial, which locks your radio onto a carrier wave at a set frequency.
A transmitter attached to a device, such as an MP3 player, uses this field to send data by modulating the field minutely in the same way that a radio carrier wave is modulated to carry information.
Thinking about it, any carrier wave would be hindered by speed, noise and signal degradation.
Modulation is the process of varying some characteristic of the electric carrier wave as transmitted information on that carrier wave fluctuates.
