But for that, you have to look at things in the time domain, something a number of readers here refuse to do for continuous sinusoidal excitation. When you look at continuous sinusoidal excitation in the time domain all the information you need about power is provided without having to resort to Pfwd and Prev. Yes, but those steady-state shortcuts often lead to a distorted view of reality. Exactly what magic happens at the instant when a system goes from the transient state to steady-state? I am unsure where you construed "steady-state" in the original passage. It is, of course, in the time domain that one can explore the non-steady state mature of the system. ....Keith |
