Input Impedance - Lesson 8

This video lesson defines the input impedance as the ratio of the total voltage at the input port to the total current at the input port. It is part of the Ansys Innovation Course: Transmission Line Theory.

Thank you so much for your content! Your presenting is wonderful. Is impressive how you manage to make videos this short, with that much information and this easy to understand and follow about this topic.

Thank you!

So clear and on point. Thank you

@ 0:42: (Vo-/Vo+ = r ) -> therefore shouldn't the equation be Vin = Vo+ (e^( g.l ) + r.e^( - g.l )) and same follows for Iin as well. Am I wrong? But, really appreciate the effort, and thanks for these videos. Very helpful in understanding the concepts. Keep up the good work!

Where are you getting gamma, little L, and Beta? Professors often say, "Here are the equations. Now run with them." Ugh.

[@emviso]

Hi Dan, Little l is defined in the first figure - it's the distance, in meters, from the load. Gamma and beta are the standard variables used to represent the propagation constant and the lossless propagation constant, respectively. If you start at the beginning of this playlist, it might help introduce things in a logical manner.
