Define modulation in computer network
WebQAM (quadrature amplitude modulation) is a method of combining two amplitude-modulated (AM) signals into a single channel, thereby doubling the effective bandwidth. QAM is used with pulse amplitude modulation (PAM) in digital systems, especially in wireless applications. WebBy Dinesh Thakur. Modem is abbreviation for Modulator – De-modulator.
