Assignment: Design two Moore FEM state transition diagrams (factored and unfactored FSIvf) for a PIN-based entry device that takes in two inputs, A and B, and it produces one output, E. Ensure that your machine is deterministic.

The machine starts in or is reset to the start state where E = fl.

After the following combination is entered for AB values, respectively: 11 9 1t} 9 G], the machine outputs E = l for two cyclesa'states. That is, it outputs E = 1 immediately after {11 is entered, and then for one more cycle irrespective of the input values. After the two cycles, it retnms back to the start state.

At all other times, the machine outputs E = II}.

For each incorrect attempt, such as 11 9 {H}, including incorrect attempts from the start state, the machine registers the attempt as failure, and the input sequence has to be entered again, starting with l 1. If there are less than three consecutive failures, then the number of failures is reset back to zero after the right combination is entered.

After three consecutive incorrect attempts, the machine goes to the locked-down mode from which it does not exit regardless of input unless it is reset. For the factored FEM, you should introduce a number of internal signals to synchronize the factored machines, but no other external signals except for the ones speci?ed above are allowed. Clearly explain your design, write explanations next to each important state, and next to each factored machine if applicable. Also, correctly label each state, write the output inside each state, include all the required transitions, and correctly label each transition.
