Hello,

I am curious about the equation 2.7(a), and trying to prove it. So, I did my own calculation, and got a different result from the textbook. Did I make a right calculation? Also, I want to know where is the time t = tr? (Since fig 2.2 begins at time t = t(k-1), not t=0)

Thank You

Hello,

Real quick, why are you integrating udc/2 ?
It seems that if you were to integrate anything, it would have some slope to it because the output is a ramp.
