#DIY #Circuit Design: Pulse Width Demodulation http://www.engineersgarage.com/tutorials/circuit-design-pulse-width-demodulation The PWM technique is used in devices like DC motors, Loudspeakers, Class -D Amplifiers, #SMPS etc. They are also used in communication field as-well. The modulation techniques like AM, FM are widely used RF communication whereas the PWM is modulation technique is mostly used in #Optical #Fiber Communication (#OFC).
