Carrier wave

In telecommunications, a carrier wave is a high-frequency waveform that is used to transmit information over a communication channel. The carrier wave serves as a foundation upon which a signal is added or modulated in order to carry information.

For example, in radio communications, the carrier wave is used to carry the audio signal that is being transmitted. The audio signal is added to or modulated onto the carrier wave, which is then transmitted over the airwaves to a receiver.

In digital communications, carrier waves are also used to carry digital signals. In this case, the digital signal is added to or modulated onto the carrier wave, which is then transmitted over a digital communication channel.

The frequency of the carrier wave is typically much higher than the frequency of the signal being transmitted. This allows for more efficient transmission of the signal over long distances, as high-frequency signals are less prone to interference and can travel further without being attenuated.

In addition to telecommunications, carrier waves are also used in other applications, such as radar and navigation systems. In these applications, carrier waves are used to transmit and receive signals that are used to determine the location of objects or to detect and track movement.

Understanding carrier waves is important in the field of telecommunications, as it is the foundation upon which many types of communication systems are built. By modulating or adding signals to a carrier wave, information can be efficiently transmitted over long distances, enabling communication across the globe.
