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=PW/T×100% Equally, a duty cycle (ratio) may be expressed as: D=PW/T where D is the duty cycle, PW is the pulse width (pulse active time), and T is the total period of the signal.
