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).
Design Frequency is the center frequency with needed bandwidth.Operating frequency is the frequency at which the communications are being made with the total bandwidth occupied by the carrier signal with modulation.Usually bandwidth of the antenna will be wider than the bandwidth of the signal so that more than one center frequency the antenna can ...
