demodulationWhen digital information is transmitted over an analog medium, such as a telephone line, an electronic waveform is modulated to contain the information. This analog signal is referred to as a carrier wave. Demodulation is the act of extracting digital data from this signal once it reaches its destination. A common example of a demodulating device is a modem.
