What is modulation, and what are the different types of modulation schemes.

Question

Accepted Answer

Modulation is the process of varying a carrier signal to transmit information. Different types include AM, FM, PM, and QAM.

Modulation is used to transfer information by varying a high-frequency carrier signal.
Amplitude Modulation (AM) varies the amplitude of the carrier signal to encode information.
Frequency Modulation (FM) varies the frequency of the carrier signal to encode information.
Phase Modulation (PM) varies the phase of the carrier signal to encode information.
Quadrature Amplitude Modulation (QAM) combines both amplitude and phase modulation to encode information.
Other modulation schemes include Phase Shift Keying (PSK), Frequency Shift Keying (FSK), and Orthogonal Frequency Division Multiplexing (OFDM).
