ries Connections Series Connections hen a transmission line is series connected When a transmission line is series connected to another transmission line, the discontinuity hat we have been calling the load (what we have been calling the load impedance) will be characterized by the input pedance at the junction of the lines impedance at the junction of the lines. This will be illustrated in the following slides McGill ECSE 352 Fall 2011 D. Davis 2
