Pwm Demodulator Circuit Diagram

This document gives an overview of how pulse width modulation and demodulation can be performed using bipolar junction transistors and operational amplifiers. The average value of voltage (and current) fed to the load is controlled by switching the supply between 0 and 100% at a rate faster than it takes the load to change significantly.
