First, Duty Cycle is the ratio of the amount of time the device is on/conducting to the total period of the device.
The comparator will only be on if the input reaches 2 volts and higher. But as the input voltage goes down again beyond 2 volts, the comparator is off. This whole cycle takes 2π units so the period is 2π.
To get the total time the comparator is on, use this formula: integral_from{π/6} to {5π/6} 1dx. Divide that to the period 2π.

That's how you will get (1/3).

For those who wants to know about Pi/6.
Vm = 4V as Vpp = 8V.
Vref = V = 2V.

As V = Vm Sin(X) So, 2 = 4Sin(X).
Sin(X) = 0.5.
X = Sin Inverse (0.5).
X = 30 or Pi/6.

Thanks all for the explanation.

I didn't know about this topic before referring here but with the elaborate explanations, I understand it better now. Thank yo all.
