## Drawing a digital waveform

### Review digital waveforms:

- You know the amplitude: 0V to 5V
- You know the shape: square wave
- If the frequency is 1Hz there is 1 cycle per second

- If the frequency is 4Hz there are 4 cycles per second, so each cycle takes 1/4 of a second or 250 mSec

### Questions about this digital waveform:

- What is the period of the waveform?

What is its frequency?

What is the duty cycle?
