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:
“I have travelled a good deal in Concord; and everywhere, in shops, and offices, and fields, the inhabitants have appeared to me to be doing penance in a thousand remarkable ways.... The twelve labors of Hercules were trifling in comparison with those which my neighbors have undertaken; for they were only twelve, and had an end; but I could never see that these men slew or captured any monster or finished any labor.”
—Henry David Thoreau (1817–1862)
“Most parents aren’t even aware of how often they compare their children. . . . Comparisons carry the suggestion that specific conditions exist for parental love and acceptance. Thus, even when one child comes out on top in a comparison she is left feeling uneasy about the tenuousness of her position and the possibility of faring less well in the next comparison.”
—Marianne E. Neifert (20th century)
“It is comparison than makes people miserable.”
—Chinese proverb.
