                                     10.42  A simple frozen wave generator is shown in Figure 10.38. Both switches are
                                           closed simultaneously at t = 0. Construct an appropriate voltage reflection
                                           diagram for the case in which R L = Z 0 . Determine and plot the load
                                           resistor voltage as a function of time.
                                     10.43  In Figure 10.39, R L = Z 0 and R g = Z 0 /3. The switch is closed at t = 0.
                                           Determine and plot as functions of time (a) the voltage across R L ;(b) the
                                           voltage across R g ;(c) the current through the battery.
