Here,
The time period is given as 4 times of pulse width.
Duty cycle= on time(positive pulse width)/((on time + off time)(i.e.Time Period)) *100.
Let P be the period.
So Duty cycle%= (P/4P)*100= 25%.

Duty cycle is defined as the ratio of pulse width to the pulse period.

Duty cycle = {ON time(or Pulse width)/Total time period (which means ON+OFF time)}*100
= (t//4t)*100
= (1/4)*100.
= 25%.

Actually duty cycle is pulse duration divided by total time period

i.e = pulse duration/total time period

So pulse width=on time + off time

i.e)total time period

DC=(1/4)*100

=25%

Duty cycle is the ratio of pulse width to the period.
Duty cycle=(tw/T)*100%
=(1/4)*100%
=25%

As known T=4tw
so the Duty cycle =tw/T*100
=tw/4tw*100
=1/4*100
=25

Duty cycle = (on time) / (on time+off time).

i.e pulse width = on time+off time.

So D.C = 1/4*100 = 25% is right.

Duty cycle= (on time) / (on time+off time).

I. E. , pulse width= on time+off time.

So D. C =1/4 *100.

=25%.

Duty cycle = pulse width/period * 100.
Given,
Period = 4pulse width,
DU = PW/4PW * 100,
= 1/4 * 100 = 25%.

Pulse width=(Ton/Ton+Toff)*100.

=1/4*100

=25%.
