Pulse modulation involves varying characteristics of pulses to represent data effectively.
Pulse modulation is a method used to represent data in the form of pulses. The three basic forms of pulse modulation are amplitude modulation (AM), frequency modulation (FM), and phase modulation. In amplitude modulation, the amplitude of the carrier wave is varied in accordance with the waveform of the message signal.
