Q15 / 100
What is PWM (Pulse Width Modulation) commonly used for in embedded systems?
Correct! Well done.
Incorrect.
The correct answer is A) Controlling the average power delivered to a device (like dimming an LED or controlling motor speed) by rapidly switching a digital signal on and off
A
Correct Answer
Controlling the average power delivered to a device (like dimming an LED or controlling motor speed) by rapidly switching a digital signal on and off
Explanation
PWM varies the proportion of time a signal is "on" versus "off" (duty cycle) within a fixed period, effectively controlling the average voltage/power delivered, used for dimming LEDs, motor speed control, etc.
