Problem 4 A generator with an internal resistance of RG = 1202 produces a 5us square pulse with an open-circuit voltage of Ve 5V. The pulse travels at half the speed of light on a 3km lossless transmission line with a characteristic impedance of Zo= 1800 that is terminated with a load resistance of R 902. Use a bounce diagram to construct a voltage vs. time plot for the voltage signal observed at the center point of the transmission line,...
