A finite state machine (FSM) is implemented using the D flip-flops A and B and logic gates, as shown in the figure below. The four possible states of the FSM are Q

_{A}Q_{B}= 00, 01, 10, and 11.Assume that X_{I}N is held at a logic level throughout the operation of the FSM. When the FSM is initialized to the state Q_{A} Q_{B} = 100 and clocked, after a few clock cycles, it starts cycling through
