Also known as signal modulation, wave modulation, waveform modulation
process of encoding information by varying properties of a periodic carrier waveform
AI overview
Modulation is a technique for sending information by changing properties of a carrier wave—such as its amplitude, frequency, or phase—in a way that encodes the message you want to transmit. It matters because it's the fundamental method used to broadcast signals over long distances in radio, television, cellular networks, and many other communication systems.
