Pulse width modulation (PWM) refers to the use of the digital output of a microprocessor to control an analog circuit, and is a method of digitally encoding the level of an analog signal. Controlling analog circuits digitally can greatly reduce the cost and power consumption of the system. A PWM controller is included in many microcontrollers.
