## How do you know if its Moore or mealy?

Mealy machines react faster to inputs. They generally react in the same clock cycle. In Moore machines, more logic is required to decode the outputs resulting in more circuit delays. They generally react one clock cycle later.

What is the final state of Moore machine?

It has no final states. Its states produce output. It does not accept or reject input, instead, it generates output from input. Lastly, Moore machines cannot have nondeterministic states.

What are the limitations of finite state machine?

• The expected character of deterministic finite state machines can be not needed in some areas like computer games.
• The implementation of huge systems using FSM is hard for managing without any idea of design.
• Not applicable for all domains.

### How many states would be there in its equivalent Moore machine?

Design a Moore machine to generate 1’s complement of a given binary number. Solution: To generate 1’s complement of a given binary number the simple logic is that if the input is 0 then the output will be 1 and if the input is 1 then the output will be 0. That means there are three states.

What is the difference between Moore and Mealy state machines?

A Mealy Machine changes its output on the basis of its present state and current input. A Moore Machine’s output depends only on the current state. It does not depend on the current input. Mealy Machine places its output on the transition.

Which automata takes stack as storage?

Explanation: Pushdown Automaton uses stack as an auxiliary storage for its operations.

## Does mealy machine accept states?

Mealy machine has accepting states. We can convert Mealy to Moore but not vice versa.

Is Moore machine deterministic?

This is in contrast to a Moore machine, whose (Moore) output values are determined solely by its current state. A Mealy machine is a deterministic finite-state transducer: for each state and input, at most one transition is possible.

What is the state diagram of a Moore machine?

The state diagram for a Moore machine or Moore diagram is a diagram that associates an output value with each state. Moore machine is an output producer. Relationship with Mealy machines As Moore and Mealy machines are both types of finite-state machines, they are equally expressive: either type can be used to parse a regular language.

### What is state transition table in Moore machine?

State transition table is a table showing relation between an input and a state. The state diagram for a Moore machine or Moore diagram is a diagram that associates an output value with each state. Moore machine is an output producer.

How is a Moore machine described by a 6 tuple?

Moore machine is an FSM whose outputs depend on only the present state. A Moore machine can be described by a 6 tuple (Q, ∑, O, δ, X, q 0) where − Q is a finite set of states.

What is the input alphabet of a Moore machine?

Moore machine is an FSM whose outputs depend on only the present state. A Moore machine can be described by a 6 tuple (Q, ∑, O, δ, X, q 0) where − Q is a finite set of states. ∑ is a finite set of symbols called the input alphabet.
