2. I made an impedance matching circuit but forgot which impedance was originally matched. Find the unknown load impedance.
What is the impedance that the 50Ohm load sees?

3. Questions How do I match impedances on Smith Chart
Why do we trace the impedance and admittance circles as reference
How come I can’t do Y=Y/Yo with a given impedance load does it work? Why? Do I just multiply by 50 to get admittance
What does the angle of the reflection coefficient mean
How do I know which curve to follow to reach the r=1 circle
Drawing the impedance matching on Smith Chart
How do we do it

5. Parallel connection between a resistor Y=2 and capacitor Y=j1 is given
Parallel connection between a resistor Y=2 and capacitor Y=j1 is given. What is the equivalent impedance for this network?

9. Practice Problem
A 50-Ohm transmission line is terminated in a ZL=100-j50 Ohms.
Design a lumped-element impedance matching circuit
Identify 4 different impedance matching circuits that you can use.
