 Jcreddy said: (Feb 12, 2011) Rise time=8ms. Total timeperiod=32ms. Dutycycle= (rise time/totaltimeperiod) *100. 8/32 (100) =25%.

 Pradeep said: (Sep 17, 2011) Thank you Jcreddy

 Padma said: (Sep 19, 2011) Duty cycle=(high time/pulse width)*100=(8 ms/32 ms)*100=25%

 Sagar Bakhuda said: (Sep 20, 2011) Duty cycle=(high time/pulse width)*100=(8 ms/32 ms)*100=25%

 Surajit said: (Mar 28, 2013) What is duty cycle?

 Cm Prasad said: (Nov 7, 2013) Can anyone define duty cycle?

 Rn Birla said: (Nov 10, 2013) The duty cycle is define as the ratio of turn on the time and total time. Duty cycle = Ton/(Ton+Toff).

 Chopra said: (Jun 13, 2015) What is the means by high time?

 Skh said: (Aug 7, 2015) High time means peak value of wave.

 Nasar Bhutta said: (Nov 28, 2015) Nice definition of duty cycle.

 Aleksandr said: (Feb 6, 2016) Duty cycle = Ton/(Ton+Toff) of pulse waveform not high time/pulse width. Dear @Jcreddy, 32ms is not total time period it's pulse width as written in question. So question is not correct.

 Nisar said: (Feb 11, 2016) @Aleksandr. It's pulse width given in time domain. Actually the x axes is in time rather in meters. So it gives time period for one complete wave.

 Marshall said: (Feb 13, 2016) At positive peak the time is 8 milliseconds or at 90 degrees. To reach 360 degrees, the time is 32 milliseconds. Therefore 8/32ms = 0.25. It means the duty cycle is 25%.

 Santosh Singh Meena said: (Sep 17, 2016) Duty cycle wave pulse are high width.

 Dhaval said: (May 3, 2017) Here, Ton + Toff = pulse width.

 Neeraj Kumar said: (May 31, 2020) Right, agree @Rn Birla.
