Integrate 8dT from 0 to 0.2T with period T and integrate 3dT from 0 to 0.8T with period T. Then add the two results.
We get 8*0.2 + 3*0.8 = 4.
We get 8*0.2 + 3*0.8 = 4.

@Drishti: why do u integrate 3dT from 0 to .8T ?? you can simply add 3 with (8*0.2), i guess the answer is 4.6

Baseline + (duty cycle*p-p amplitude) = Average voltage.
Baseline = 3V.
Duty cycle = 0.2.
p-p amplitude = amplitude-baseline = 8V-3V = 5V.
3 + (0.2*5) = 3+1 = 4V average voltage.
Baseline = 3V.
Duty cycle = 0.2.
p-p amplitude = amplitude-baseline = 8V-3V = 5V.
3 + (0.2*5) = 3+1 = 4V average voltage.

Can any one tell me what is meant by baseline voltage?

Answer would be B.
4.6 v because I have a reason 3 v be dc wave and (baseline +(p-p*duty cycle)) = (3+(8*0.2)) = 3+1.6 = 4.6 v.
4.6 v because I have a reason 3 v be dc wave and (baseline +(p-p*duty cycle)) = (3+(8*0.2)) = 3+1.6 = 4.6 v.

@Giri.
The baseline value may be back EMF value. So we should consider the waveform from above baseline value.

Integrate 8 dT from 0 to 0.2 and integrate 3 dT from 0.2 to 1. Then add the two results.
So we get (8*0.2)+(3*0.8) = 4.
So we get (8*0.2)+(3*0.8) = 4.
