Senior Electronics Engineer Interview Questions and Answers

PWM stands for Pulse Width Modulation. It is a technique used to control the amount of power delivered to a load.

• PWM involves rapidly switching a signal on and off to control the average voltage or current delivered to a load.

• It is commonly used in motor control, LED dimming, and power regulation.

• The duty cycle of the signal determines the amount of power delivered to the load.

• Higher duty cycle means more power delivered, while lower duty cycle means less power delivered.

• PWM ...read more
