A generator circuit with Vg = 200 V and Rg = 25 was used to excite a 75-lossless line with a rectangular pulse of duration 0.4 μs. The line is 200 m long, its up = 2 x 108 m/s, and it is terminated in a load ZL =125.
(a) Synthesize the voltage pulse exciting the line as the sum of two step functions, Vg1 (t) and Vg2 (t).
(b) For each voltage step function, generate a bounce diagram for the voltage on the line.
(c) Use the bounce diagrams to plot the total voltage at the sending end of the line.
