Comparison
Output values :
- A Mealy machine is determined both by its current state and by the values of its inputs.
- A Moore machine is determined solely by its current state.
The number of states in a Moore machine will be greater than or equal to the number of states in the corresponding Mealy machine. This is due to the fact that each transition in a Mealy machine can be associated with a corresponding, additional state mapping the transition to a single output in the Moore machine, hence turning a possibly partial machine into a complete machine.
The diagram :
- for a Moore machine associates an output value with each state
- for a Mealy machine associates an output value with each transition edge

Famous quotes containing the word comparison:
“In everyone’s youthful dreams, philosophy is still vaguely but inseparably, and with singular truth, associated with the East, nor do after years discover its local habitation in the Western world. In comparison with the philosophers of the East, we may say that modern Europe has yet given birth to none.”
—Henry David Thoreau (1817–1862)
“The difference between human vision and the image perceived by the faceted eye of an insect may be compared with the difference between a half-tone block made with the very finest screen and the corresponding picture as represented by the very coarse screening used in common newspaper pictorial reproduction. The same comparison holds good between the way Gogol saw things and the way average readers and average writers see things.”
—Vladimir Nabokov (1899–1977)
“Clay answered the petition by declaring that while he looked on the institution of slavery as an evil, it was ‘nothing in comparison with the far greater evil which would inevitably flow from a sudden and indiscriminate emancipation.’”
—State of Indiana, U.S. public relief program (1935-1943)
