Exercise 54

A sinusoidal voltage generator with V g = 0.1 /0 ° (V) and internal impedance 50 (Ω ) is connected to a lossless transmission line having a characteristic impedance R 0 = 50 (Ω ) . The line is /8 long and is terminated in a load resistance R L = 25 (Ω ) . Find (a) V i , l i , V L , and I L ; (b) the standing-wave ratio on the line; and (c) the average power delivered to the load. Compare the result in part (c) with the case where R L = 50 (Ω ) .
