Study Notes
Pulse Width Modulation (PWM)
- In Pulse Width Modulation (PWM), the width of the pulses is varied.
- The term 'width' in PWM refers to the duration of the pulses.
- The amplitude of the constant amplitude pulses is not varied, but the width of the pulses is varied proportional to the amplitude of the modulating signal.
Test your knowledge of pulse width modulation with this quiz. Learn about the active portion of the duty cycle and how it varies based on the amplitude of the analog signal.
