Find the input impedance for the networks, assuming that the loads are ZL=200 Ohms and the transmission lines have characteristic impedances of Zo=100 Ohms and length λ/4. Also find the reflection coefficient Γin at the inputs to the networks assuming that the networks are driven from 50 Ohm sources.


ANS for
Γin=0
or
Γin=-0.33
