Exercise 55

Measurements on a lossless transmission line of characteristic re­sistance 75 (Ω ) show a standing-wave ratio of 2.4 and the first two voltage minima nearest to the load at 0.335(m) and 1.235(m). Use a Smith chart to: (a) determine the load impedance Z L , and (b) find the location nearest to the load and the length of a short-circuited stub required to match Z L to the line.
