This document discusses finite state machines (FSMs) and compares Moore and Mealy machines. Moore machines output depends only on the current state, while Mealy machines output depends on both the current state and input. It provides examples of Mealy machine applications like traffic lights and vending machines. Mealy machines have advantages like reducing the number of states needed and generating faster output that changes immediately with input changes.

- 3. A finite-state machine, or FSM for short, is a model of computation based on a hypothetical machine made of one or more states. Only a single state can be active at the same time, so the machine must transition from one state to another in order to perform different actions. FSMs: Moore/Mealy Machines 3
- 4. MOORE The output of a Moore finite state machine depends only on the machine's current state; transitions are not directly dependent upon input. MEALY In the theory of computation, a Mealy machine is a finite state transducer that generates an output based on its current state and input. This means that the state diagram will include both an input and output signal for each transition edge. 4

- 8. Mealy Model: Mealy leads to reduction in number of states Mealy is faster because output will change as soon as input changes. 8
