5) Consider the circuit shown in Figure 3a whose current inputs are as shown. a) Is this a combinatorial circuit? b) On the figure, trace the circuit after the clock signal and E are set to 1. c) What is the value of the output Q after D, E, and the clock signal drops to 0? d) Give the values of D and E required make Q = 0 when the clock rises.
