    As a formula, a duty cycle (%) may be expressed as: [2] Equally, a duty cycle (ratio) may be expressed as: where is the duty cycle, is the pulse width (pulse active time), and is the total period of the signal. Thus, a 60% duty cycle means the signal is on 60% of the time but off 40% of the time.
