Draw the logic diagram of the circuit

Question

Problem

A sequential circuit with two D flip-flops, A and B, one input X, and two outputs, Y and Z, is specified by the following input and output equations:

D_A = B
D_B = (X ⊕ A)'
Y = B
Z = (X ⊕ A) ⊕ B

1) Draw the logic diagram of the circuit.
2) Derive the state table for the circuit.
3) Derive the state diagram for the circuit.
