Suppose the voltage waveform shown in Fig. 2-45 was observed at

Suppose the voltage waveform shown in Fig. 2-45 was observed at the sending end of a 50-??transmission line in response to a step voltage introduced by a generator with Vg = 15 V and an unknown series resistance Rg. The line is 1 km in length, its velocity of propagation is 1 x 108 m/s, and it is terminated in a load ZL = 100 ?.
(a) Determine Rg.
(b) Explain why the drop in level of V (0) at t = 6 Âľs cannot be due to reflection from the load.
(c) Determine the shunt resistance Rf and the location of the fault responsible for the observed waveform.
