MCQ Practice Question

Which statement correctly distinguishes a Moore machine from a Mealy machine?

AMoore output depends only on present state, while Mealy output can depend on present state and input
BMoore has no states
CMealy output depends only on the clock frequency
DMoore cannot be implemented with flip-flops

Correct Answer: A. Moore output depends only on present state, while Mealy output can depend on present state and input

Explanation: In a Moore FSM, outputs are functions of state only. In a Mealy FSM, outputs are functions of both present state and current inputs.

Reference: Standard digital electronics: Moore and Mealy machines
