Consider four lossless transmission lines, each with a characteristic impedance and one-way time delay ta, as shown in the figure below. The main line is excited at t = 0 by a step voltage source of amplitude 10V with a source resistance of Zo. VL1 = tas = 1 ns Rs - Zo Z04 = 3%0 RL1 Vs tuz = 1 ns Zo2 = Zo Zo + 10V S Zo1 = Zo switch S₁ td1 = 2 ns RL3 - %0 a) Noting that the switch S₁ remains open, draw a bounce diagram for the transmission line system. Determine and sketch the voltages Vs(t) and VL₁(t) for 0≤t≤ 6 ns. Your 'sketches' should be quantitative and unambiguous, clearly specifying each of the break points along the time axis as well as the vertical axis. b) Now assume that at t = 6 ns switch S₁ is closed. Draw a bounce diagram and sketch the voltage Vs(t) and V₁₁(t) for 6 ≤ t ≤ 12 ns. Your 'sketches' should be quantitative and unambiguous, clearly specifying each of the break points along the time axis as well as the vertical axis. RL2 = 320 Zo3 = Zo td4 = 1 ns
