Victor, the window is a sine from 0 to pi that is exponentiated. Outside [0, pi] there are just copies of the window (some negative if the exponent is odd). I don't see how that is truncated. I understand "truncating" to mean that you have some non-periodic function like a gaussian or tanh() from which you take a finite portion. Of course if I just integrate sin^n without DC correction I get rising stairs from -inf to inf. What I do instead is this: one period of the impulse train is composed of the window and some "dead time" after that. The whole thing is DC corrected so that integration gives a periodic sawtooth.
