Duty Cycle Calculator

This calculator determines the duty cycle of a signal based on its on-time and period. The duty cycle is expressed as a percentage and represents the fraction of one period in which a signal is active.

Calculation Results

Calculation Formula

Duty Cycle (%) = (On-Time / Period) × 100%

Where:
- On-Time: The duration the signal is active
- Period: The total duration of one complete cycle

What is Duty Cycle?

The duty cycle is a measure of the fraction of time a signal is active within one complete period. It is commonly used in various fields such as electronics, signal processing, and telecommunications.

How to Use the Calculator

  1. Enter the On-Time (the duration the signal is active) in seconds.
  2. Enter the Period (the total duration of one complete cycle) in seconds.
  3. Click the Calculate button to compute the duty cycle.
  4. The result will be displayed as a percentage.

Example

If a signal is active for 2 seconds and has a period of 10 seconds, the duty cycle would be calculated as follows:

Duty Cycle = (2 seconds / 10 seconds) × 100% = 20%

Applications

Duty cycle calculations are essential in various applications:

  • Control systems for motors and lights
  • Signal modulation in communications
  • LED flashing patterns
  • Timing circuits in electronics
