Modulation is the process of varying one or more properties of a periodic waveform (the carrier signal) with a modulating signal, which typically contains the information to be transmitted. When transmitting digital data over an analog medium (like telephone lines or radio waves), the digital signal is used to modulate an analog carrier. This process effectively converts the digital information into an analog signal that can be transmitted.
