In the system shown in Fig. 1. the transmission lne is terminated with a load consisting of a resistor Ri - 1000 and capacitor Ci 0 pF connected in parallel. The switch is closed at t-0 The signal generator produces a short square pulse 40 ns in length, and with an amplitude of t0 V. The signal generator resistance is R;\"100 · the characteristic impendance is Z.-100 , and the sural period on the transmission line is T 100 ns 2. Fig. I Parallel capacnor and resistor attached to the transinission line Determine the time constant r ) Plot the load voltage vi(i) as a function of time i >T

Solution

= time constant = R1*C

VL =V M ( 1- E-t/rc)
