A carrier signal is also known as a carrier wave. It refers to an electrical waveform that is used to transmit information over a communication system. There are a few other synonyms associated with a carrier signal, including a carrier frequency, carrier wave frequency, or simply a carrier. In telecommunication, a carrier signal is used to carry voice, data, and video signals. It provides a continuous transmission medium for data that is modulated onto it. The term "carrier" implies that it carries other signals and hence, it can also be referred to as a particular frequency band allocated for a particular type of transmission. Other synonyms associated with a carrier signal include carrier tone, modulating frequency, and subcarrier signal.
