Mealy Machines

A Mealy machine is a type of simple computational model used in digital logic and automata theory. It processes sequences of inputs and produces outputs based on both the current input and its current internal state. Think of it as a state machine that "remembers" what has happened so far and responds accordingly; the output is generated immediately in response to each input and state combination. Mealy machines are efficient because they generate outputs quickly, depending directly on inputs without needing to wait for a new state change. They are widely used in designing digital circuits, controllers, and communication protocols.
