Given a sequential circuit (shown in the figure below) that has two D flip-flops A and a) [2 marks] Write the logic function for the flip-flops inputs DA and DB, as a b) fI mark] Write the logic function for the output Z as a function of A and B c) /3 marks/ Ifthe present state ofA and B are A = 0 and B = 1, and the circuit B, two inputs X and Y, and one output Z. function of X, Y, A and B 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? DA Clock DB
