Given a sequential circuit (shown in the figure below) that has two D flip-flops A and B, two inputs X and Y, and one output Z. [2 marks] Write the logic function for the flip-flops inputs DA and DB, as a function of X, Y, A and B. a) b) [I mark] Write the logic function for the output Z as a function of A and B. [3 marks] If the present state of A and B are A inputs are X-0 and Y 1 Then, what will be the next state values for the flip-flops A and B? What will be the value of output Z, in this case? c) -0 and B 1, and the circuit Clock DB
