3.9 A loss-free line divides into two sections A and B. The length of section A is 10 cm and that of section B is 14.5 cm. The impedances of the loads connected to the two sections of line are 166 + j60 2 on to A and 37.5 + jo on to B. The frequency of operation is 258 MHz and the characteristic impedance is 100 2. Calculate the voltage-reflection coeffi- cient on each line and also the v.s.w.r. on the source side of the junction.
