Summary

This is easy to learn lecture note for moore and mealy machine....

Description

Moore Machine It is defined as a machine in which the output symbol depends upon the present state of a machine.    

There is no final state in Moore machine. They cannot be used for language acceptance. (n+1) output symbols can be produced for n input symbols. They are also used for type conversion of a language.

Mealy machine It is a finite automaton in which the output is associated with each transition and not with states.  No final state in mealy machine.  n output symbols are produced for n input symbols. Mealy machine can be represented by a diagram where the output of state is written along with the input symbols by using a slash(/). Difference between Moore and mealy machine Moore

Mealy

Moore machine can be converted to

Mealy machine can be converted to

mealy machine. Length of moore machine is one longer

moore machine. Length of mealy machine is one lesser

than mealy machine for given input. Output should be associated with the

than moore machine for given input. Output of the input will be along the

state increase of moore machine. Moore machine’s output depends only

edges in case of Mealy machine. Mealy machine’s output depends only

on the current state.

on the current state as well as on the inputs....
