(30 points) Consider the following state machine: (a) Is this a Mealy or Moore machine? Explain. Moore. The output depends only on the state values. (b) Derive excitation equations (equations for the J and K inputs) for both J-K flip-flops. J1 = IN*Q0 K1 = IN J0 = IN K0 = IN + Q1 (c) Using the characteristic equation for a J-K flip-flop (Q* = JQ + KQ), derive the transition (next state) equations for both J-K flip-flops. Q1* = IN*Q0*Q1 + (IN)*Q1 = IN*Q0*Q1 + IN*Q1 Q0* = IN*Q0 + (IN + Q1)*Q0 = IN*Q0 + IN*Q1*Q0 (d) Create the transition table and the state diagram, and explain the function of this circuit. For each state in the state diagram, give the binary values of the states and the output value....
