Hello. I am watching this video: https://www.youtube.com/watch?v=xIQtnQ9XPbE and he says there: I see that the wave turns into a "normal" sinus in the end, but it's not constant. I think, that even on an unmatched transmission line, the waves should go back and forth, but eventually turn into a constant voltage. Isn't that correct? If not, and the correct answer is that the steady state IS the final wave there - how do I calculate the voltage? is it the RMS of the wave? Thank you.
