Question

Past exam question, 2010 The following questions concern the voltage V(z, t) along a 3-m long lossless line characterised by Zo = 50 and u, 0.66c. The line is fed by Ug = 80 V, and Ra a step voltage at t 0 with generator voltage = 752. The line is terminated with ZL = 252 (a) Compute the voltage reflection coefficients at both the load and generator ends, and show that the travel time along the line is 10ns. (b) What is the line voltage half-way down the line at t 10ns, and what does this voltage eventually limit to as t -+oo? 40ns (c) Draw a bounce diagram to plot V(t) at a point 2m along the line from t 0 to t
