Carrier-frequency definition

The transmission of a fixed frequency that has been altered (modulated) to "carry" data. The frequency is measured in Hertz (cycles per second). See carrier, Hz, FDM and TDM.

A frequency capable of being modulated by an information-bearing signal of another frequency or frequencies.The carrier frequency is referred to as the center frequency in Frequency Modulation (FM), as the carrier frequency is used as a centerpoint, or reference point, with higher and lower frequency signals used to represent 1 bits and 0 bits. See also carrier and frequency.
