Homework $10$

$1.$ The ASM chart below describes the operation of a synchronous FSM with scalar binary input and output signals denoted with characters from A to E$.$ Upon initialization the system enters the top state box as shown in the figure.

a$)$ Identify the names of inputs and outputs, specify output types $($Mealy$,$ Moore$),$ identify the number of states, assign state codes to state boxes.

b$)$ Implement the system with any number of D$-$flip$-$flops: obtain the flip$-$flop input excitation equations, and the equations for the output forming logic. Implement the flip$-$flop input excitation and output forming logic equations with any number of $2-$to$-1$ multiplexers, inverters can be used. Sketch the complete circuit schematic including D$-$flip$-$flops, flip$-$flop input excitation and output forming logic.
