A 50-Ohm line is terminated by a (60 +j60) Ohm load. An adjustable shorted shunt stub is placed 0.23 Lambda from the load. What is the smallest standing wave ration that can be achieved between the generator and the line by adjustment of the stub length? What was S before the stub was added? Now instead of placing the stub at 0.23 Lambda, find two possible stub locations and their respective lengths to match the impedance if the stub has Z0 = 50 Ohm. Repeat (b) if Z0 for the stub is 75 Ohm.
