Pulse Width Modulation (PWM) is a very common technique in telecommunication and power control. it is commonly used to control the power fed to an electrical device, whether it is a motor, an LED, speakers, etc. It is basically a modulationtechnique, in which the width of the carrier pulse is varied in accordance with the …
Pulse Width Modulation (PWM) is a powerful technique where width of the pulse is changed by keeping the frequency constant. The technique is used in many control systems today. The application of PWM is not limited and it is used in wide range of applications such as motor speed control, measurement, power control and communication etc. …
