A Pulse width modulator (PWM) is a circuit which modulates a signals pulse width, this is usually done to convey either information over a communication channel or to control the amount of power sent, to a load over a set periodicity.  These loads can include DC motors or LEDs. An analog signal has a continuously varying value, with infinite resolution both in time and magnitude. A PWM is used to digitally encode an analog signal levels by applying voltage over controlled intervals of time.
