In telecommunications, a carrier wave, carrier signal, or just carrier, is a waveform (usually sinusoidal) that is modulated (modified) with an information-bearing signal for the purpose of conveying information. This carrier wave usually has a much higher frequency than the input signal does.

What is carrier signal and its role in analog signal?
In analog transmission, the sending device produces a high-frequency signal that acts as a base for the information signal. This base signal is called the carrier signal or carrier frequency. The receiving device is tuned to the frequency of the carrier signal that it expects from the sender.
What is carrier signal and modulating signal?
Modulation is defined as the process of superimposing a low-frequency signal on a high-frequency carrier signal. Or. The process of varying the RF carrier wave in accordance with the information in a low-frequency signal.
What is carrier frequency communication?
Carrier frequency is defined as the frequency of a carrier wave, measured in cycles per second, or Hertz, that is modulated to transmit signals.
