A 2 V signal is incident to the interface from a 75 Ohm region propagating to a 50 Ohm impedance region. What is the reflection coefficient? What is value of the incident, reflected and transmitted wave? What voltage would you measure on either side of the interface right after the signal goes through the interface. For the interface, I'm a little confused. I used a voltage divider and got V_transmitted = 0.8 and V_incident = 1.2. But shouldn't they be the same?
