This metric is crucial in electronics, welding, and signal processing to evaluate performance in PWM (Pulse Width Modulation), timers, and switches. A higher duty cycle means the device or signal is active more frequently, impacting efficiency and performance.
Formula:
| Variable | Description | Unit |
|---|---|---|
| D | Duty cycle | Percentage (%) |
| PW | Pulse width (active time) | Seconds (s) |
| T | Total period of the signal | Seconds (s) |
Solved Calculations:
Example 1: Calculating Duty Cycle for a Signal with PW = 2ms and T = 10ms
| Step | Value | Explanation |
|---|---|---|
| Pulse Width (PW) | 2 ms | The active time of the signal |
| Total Period (T) | 10 ms | Total cycle duration |
| Divide PW by T | Calculate the ratio | |
| Multiply by 100 | Convert to percentage | |
| Result | 20% | Duty cycle of the signal |
ย
Example 2: Calculating Duty Cycle for a PWM Signal with PW = 5ms and T = 20ms
| Step | Value | Explanation |
|---|---|---|
| Pulse Width (PW) | 5 ms | The active time of the signal |
| Total Period (T) | 20 ms | Total cycle duration |
| Divide PW by T | Calculate the ratio | |
| Multiply by 100 | Convert to percentage | |
| Result | 25% | Duty cycle of the signal |
