What Modulates and Demodulates Signals?

Modulation and demodulation
Modulation is the process of encoding information in a transmitted signal, while demodulation is the process of extracting information from the transmitted signal. ... A cable modem uses network data to modulate the cable service carrier signal.

Which device is used to modulates and demodulates signals?

MODEM: Modem stands for Modulator-demodulator. It converts the analog signals from the transmission wires into digital signals which can be read by the computer devices (modulation). Then conversion of digital signal into analog and extracting out the useful information (demodulation) takes place.

What is modulation of a signal?

Modulation is the addition of information to an electronic or optical carrier signal. In electronics and telecommunications, modulation is the process of varying one or more properties of a periodic waveform, the carrier signal, with a modulating signal that typically contains information that is to be transmitted.
