1. The problem statement, all variables and given/known data Attached is the problem. I am a little confused as to how I should be approaching this type of problem. If I Determine the input impedance for the first segment of transmission line and load impedance on the right, is that going to be in parallel with [itex]Z_L[/itex] on the left? I am assuming that "effective impedance" is referring to that total input impedance at the left of the diagram, but I am unsure.
