Can anyone give me an answer Consider a transmission line with characteristic impedance Z?. This transmission line is terminated in Zo. The input impedance is (A) 4 Z (B) 2 Z (C) Z (D) Z /2

A transmission line with a characteristic impedance Zc that is loaded by ZL will show an impedance at its input that varies with its length.

I recently had an interview where they asked me the same type of question - - - Updated - - - Your answer is right. Can you tell me how you got it

Of course the answer is neither if the Zc is different than ZL. Click to expand... Right. The question makes only sense if Z = Zo. Most likely the question was quoted incorrectly. Can you tell me how you got it Click to expand... E.g. by reading a text book. See "matched load" paragraph in this article. https://en.wikipedia.org/wiki/Transmission_line#Matched_load
