Exercise 37

Consider a lossless transmission line.
(a) Determine the line's characteristic resistance so that it will have a minimum possible standing-wave ratio for a load impedance 40 + j30 ( ).
(b) Find this minimum standing-wave ratio and the corresponding voltage reflection coefficient.
(c) Find the location of the voltage minimum nearest to the load.
