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

\[ D_A = XA + \overline{X}Y, \quad D_B = XB + \overline{X}A, \quad Z = \overline{X}B \]

(a) Draw the logic diagram of the circuit.

(b) Derive the state table.

(c) Derive the state diagram.

(d) Is this a Mealy or a Moore machine?
