arallel onnections Parallel 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
arallel onnected Circuit Parallel Connected Circuit Figure 1: Two transmission lines in Parallel. The first line is series connected to the source and terminated by the junction of the two transmission lines. Each parallel line is terminated y a load by a load. McGill ECSE 352 Fall 2011 D. Davis 3
