Abstract
A simple, fast, easily designed circuit for demodulating a PWM signal produces an output signal indicating a duty cycle of a received PWM signal. The circuit may include a low pass filter circuit to receive a Pulse Width Modulated (PWM) signal and produce a triangular signal, a track-and-hold circuit to receive the PWM signal and the triangular signal and produce a minimum and maximum signals corresponding to minimum and maximum values of the triangular signal during each cycle of the PWM signal, and an averaging circuit to receive the minimum signal and the maximum signal and produce, by averaging the values of the minimum signal and the maximum signal, the output signal.
