Theory Of Computation | (TOC)Moore Machine
Moore machine is an FSM whose outputs depend on only the present state. A Moore machinecan be described by a 6 tuples M = (Q, 危, 螖, 饾浛, 位, q0)
Q = 铿乶ite set of states.
危= finite set of symbols called the input alphabet.
螖= finite set of symbols called the output alphabet.
饾浛= input transition function where 饾浛: Q✕危→Q
位= output transition function where 位: Q→螖
q0= initial state from Where any input is processed (q0∈Q).
For Example:
A transition table for Moore Machine is like:Transition Table.

Input To The Machine: 00110
OUTPUT From The Machine 000100
In Mealy Machine, if input length = n, then output length = n+1.
Theory Of Computation | Mealy Machine
A Mealy Machine is an FSM whose output depends on the present state as well as the present input. In this model, all the de铿乶ition is same as Moore machine except the output mappingfunction 位.
It can be described by 6 tuples M = (Q, 危, 螖, 饾浛, 位, q0)
Where,Q = 铿乶ite set of states.
危= finite set of symbols called the input alphabet.
螖= finite set of symbols called the output alphabet.
饾浛= input transition function where 饾浛: Q✕危→Q
位= output transition function where 位: Q✕危→螖
q0= initial state from where any input is processed (q0∈Q).
