What is FSM and explain the differences between the Mealy and Moore machines?

Question

Accepted Answer

FSM stands for Finite State Machine. Mealy and Moore machines are two types of FSMs with differences in output.

FSM is a mathematical model used to describe the behavior of a system with a finite number of states.
Mealy machines produce outputs based on both the current state and the inputs.
Moore machines produce outputs based only on the current state.
Mealy machines have more flexibility in generating outputs, while Moore machines are simpler to design and analyze.
Example: In a Mealy machine, a state transition from state A to state B with input X may produce output Y, while in a Moore machine, the output Y would be associated with state B only.

Accepted Answer

Mealy machine output depend on both upon current state and current input whereas Moore output depend only the current state
