Mealy machine

A Mealy machine is a type of computational model used in digital logic and automata theory. It processes inputs step-by-step, changing its internal state accordingly, and produces outputs based on both the current state and the received input. Think of it like a vending machine: when you press a button (input), the machine's internal status (state) determines what it dispenses (output). This model is efficient for designing systems where outputs depend directly on both input signals and the current state, making it a useful tool in designing digital circuits, control systems, and communication protocols.
