PWM Modulation and Demodulation Trainer

PWM Modulation and Demodulation Trainer is useful training product for students to understand the concept of Modulation and Demodulation. Pulse width modulation (PWM) is a technique used for controlling analog circuits with processor’s digital outputs. PWM is a way of digitally encoding analog signal levels. The duty cycle of a square wave is modulated to encode a specific analog signal level. The PWM signal changes the width at any given instant of time.
