In telecommunications, a carrier signal, carrier wave, or just carrier, is a waveform (usually sinusoidal) that is modulated (modified) with an input signal for the purpose of conveying information.This carrier wave is usually a much higher frequency than the input signal.n the case of single-sideband modulation (SSB), the carrier is suppressed (and in some forms of SSB, eliminated). The carrier must be reintroduced at the receiver by a beat frequency oscillator (BFO).
The audio information in a TV channel is a frequency modulated carrier. placed 4.5 MHz above the visual carrier at less than 1/8 of its power. Figure 1.1 (a) doesn't show the aural carrier. The aural signal frequency. modulates onto the RF carrier, thus becoming its sideband. 1 - 1.
