Pulse modulation is a type of modulation in which the signal is transmitted in the form of pulses. It can be used to transmit analogue information. In pulse modulation, continuous signals are sampled at regular intervals.

Where is pulse amplitude modulation used in communication?
PAM is mostly applied in non-based modulating transmission of digital data and applications replaced by pulse-code modulation and pulse-position modulation. Particularly all phone modems faster than 300 bit/s use quadrature amplitude modulation.
What are the types of pulse modulation?
Pulse modulation is further divided into analog and digital modulation. The analog modulation techniques are mainly classified into Pulse Amplitude Modulation, Pulse Duration Modulation/Pulse Width Modulation, and Pulse Position Modulation.
What is the function of pulse modulator?
A device that converts an analog information signal to a pulse format. A pulse modulator encodes the amplitude information at a particular time by a set of short- or long-duration pulses using such methods as pulse-amplitude, pulse-width, pulse-position, pulse-density, or pulse-code modulation.
