Question: The normalized load on a lossless transmission line is 2 + j 1. Let = 20 m and make use of the Smith chart

The normalized load on a lossless transmission line is 2 + j 1. Let λ = 20 m and make use of the Smith chart to find

(a) The shortest distance from the load to a point at which z_in = r_in + j0, where r_in > 0;

(b) z_in at this point.

(c) The line is cut at this point and the portion containing z_L is thrown away. A resistor r = r_in of part (a) is connected across the line. What is s on the remainder of the line?

(d) What is the shortest distance from this resistor to a point at which z_in = 2 + j1?
