Question 2 (50 marks) a) Figure 2 shows a sequential logic circuit with four flip-flops (X0, X1, X2 and X3 ) with external clock (input pulses) applied to the clock input of the first flip-flop. Use MMLogic to build the logic circuit shown in Figure 2. Save your design as BK9999_q2, where 9999 are the last 4 digits of your matrix no. (20 marks) b) Simulate the circuit by applying 16 pulses. For each clock pulse write down the values of X0 to X3 (20 marks) c) Based on your answer in b), what is the function of the circuit given in Figure 2. (10 marks)
