A sequential circuit with two D flip-flops, A and B; two inputs x and y; one output z; is specified by the following next-state and output equations:
A(t 1) = x' y x A
B(t 1) = x' B x A
Z = B
a) Draw a logic diagram of the circuit.
b) List the state table for the sequential circuit.
c) Draw a corresponding state diagram
d) Is this sequential circuit a Moore model or a Mealy model?
