This practice problem would be best help to me if you provide steps to help me understand, thanks in advance!

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. A(t+1)=xy+xAB(t+1)=xB+xAz=B a. Draw the logic diagram of the circuit. b. Derive the state table (use the second form). c. Derive the state diagram using the result from Q-b (please also include the output in the circle to represent each state)
