Pulse-width modulation (PWM) is a technique used to encode a message into a pulsing signal. It involves varying the width of the pulses in a signal while keeping the frequency constant. This modulation method is commonly used in various applications, including controlling the power delivered to electronic devices, transmission of information, and generating analog signals.
