Duty cycle

Common card · No. 287032

A duty cycle or power cycle is the fraction of one period in which a signal or system is active. Duty cycle is commonly expressed as a percentage or a ratio. A period is the time it takes for a signal to complete an on-and-off cycle. As a formula, a duty cycle (%) may be expressed as: D = P W T × 100 % {\displaystyle D={\frac {PW}{T}}\times 100\%} Equally, a duty cycle (ratio) may be expressed as: D = P W T {\displaystyle D={\frac {PW}{T}}} where D {\displaystyle D} is the duty cycle, P W {\displaystyle PW} is the pulse width (pulse active time), and...
