## What is Duty Cycle?
Duty cycle is the fraction of one period during which a signal is in its active (high) state.
### Formula
**Duty Cycle = On Time / Period x 100%**
**Off Time = Period - On Time**
Duty cycle is fundamental to PWM (Pulse Width Modulation), which controls motor speed, LED brightness, and power delivery by varying the on-time while keeping frequency constant.

Exemple Résolu
A 1 kHz signal with 500 microsecond on-time.
- Duty cycle: 500 / 1000 x 100 = 50.0%
- Off time: 1000 - 500 = 500 microseconds
- Frequency: 1,000,000 / 1000 = 1000 Hz
