What is Characteristic Impedance?
... In a Zen sort of way, “be the signal”, and travel down this transmission line at 6 inches/nsec. What do you see? In the first 10 psec, you have “walked” about 0.06 inches down the line. Let’s freeze time and look at the line. Behind you, you have left a wake of a constant voltage of 1 volt between t ...
