Solution

Ans) Duty cycle = Ton/T and T=Ton +Toff

a) Ton=(3-2) = 1 micro sec

   Toff=(6-3)= 3 micro sec

Duty Cylce =1/(1+3)=1/4=0.25

Duty Cylce =0.25 or 25%

------------------------------------------

b)

Ton=(20-0) = 20 milli sec

Toff=(30-20)= 10 milli sec

Duty Cylce =20/(20+10)=20/30=0.6667

Duty Cylce =0.6667 or 66.67%
