Digital Electronics Finite State Machines

For the same behavioral specification, a Mealy state machine can often use fewer states than an equivalent Moore machine because?

AIts outputs may respond directly to inputs as well as state
BIt contains no combinational logic
CIt does not use a clock
DIt stores multiple analog levels

Show AnswerHide AnswerReport an error

Correct Answer: A. Its outputs may respond directly to inputs as well as state

Explanation: Because Mealy outputs can depend directly on current inputs, some output distinctions that require separate Moore states can be represented without adding states.
