Rise time=8ms.

Total timeperiod=32ms.

Dutycycle= (rise time/totaltimeperiod) *100.

8/32 (100) =25%.

Thank you Jcreddy

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

Duty cycle=(high time/pulse width)*100=(8 ms/32 ms)*100=25%

Thanks Jcreddy.

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).

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.

@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.

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%.

Duty cycle wave pulse are high width.

Here, Ton + Toff = pulse width.
