Ep 002: Duty Cycle and Pulse Width Modulation How to Dim an LED 

In this video, we show how the percentage of time that a binary signal is a logic one translates to its use as a control signal by means of pulse width modulation.
Take aways: At the completion of this lesson, each student should be able to:
• define the term duty cycle,
• explain the importance of duty cycle with respect to digital signals, and
• calculate the duty cycle of a periodic pulse train.
