3) Consider the circuit shown in the figure with an ideal unit step source connected to a lossless line of characteristic impedance Zo = 500 having an open-circuited termination at the other end. Assuming a one-way propagation delay across the line of td, use a bounce diagram to sketch the load voltage V(t) versus time for 0 ≤t ≤10td. 1V 0 Zo, 'd 411
