Q4 Suppose the voltage waveform shown in Figure Q4a was observed at the sending end of a 50 2 transmission line in response to a step voltage introduced by a generator with V, =15 V and an unknown series (a) resistance, R. . If the line is 1 km in length, velocity of propagation for the signals on the line is 1x10 m/s, and it is terminated in a load, Z, =100 Q: (i) Determine R. (ii) Explain why the drop in level of V (0,t) at 1=6µs could only have been caused by a fault on the line and cannot be due to reflection from the load. (iii) Determine the location of the fault responsible for the observed
