Hi,
I have a couple questions regarding a homework problem and would really appreciate some help.
Consider the lossless 50ohm transmission line shown below, which has an LC circuit inserted at some point along the line. If I want to find the input impedance how would I approach this problem? As far as I know, the characteristic impedance (Zo) is the same throughout the line since its independent of the length of the line. I'm thinking I should first treat the LC load as my load, take length=0.06lambda and find the input impedance as seen from the very far left of the circuit. Then I would do the same thing on the second part of the circuit and just add the two impedances, however I'm not sure if this is the correct reasoning.
Edit: I think that the two impedances found out with the above method might have to be considered in parallel to each other not in series.
