One of the mysteries of the English language finally explained.
A high-frequency electromagnetic wave modulated in amplitude or frequency to convey a signal.
- ‘Modulation is the process of varying some characteristic of the electric carrier wave as transmitted information on that carrier wave fluctuates.’
- ‘This concept is frightening to most radio frequency engineers as it denies the need for a carrier wave.’
- ‘Thinking about it, any carrier wave would be hindered by speed, noise and signal degradation.’
- ‘The carrier wave broadcast from a radio tower is very weak by the time it reaches your set, but it is essentially electrical power.’
- ‘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 transmitter mixes the signal with some strong radio signals called carrier waves.’
- ‘This signal was then used to ‘modulate ‘a radio wave called a carrier wave - the wave that actually transmits the signal.’’
- ‘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.’
