What is the primary difference between a Mealy Machine and a Moore Machine?

• In a Mealy Machine, the outputs depend only on the current state.

• In a Moore Machine, the outputs depend only on the current state.

• In a Mealy Machine, the outputs depend on the current state and the input.

• There is no difference; both machines function identically.
