## How do you read a state machine?

In simpler terms, a state machine will read a series of inputs. When it reads an input, it will switch to a different state. Each state specifies which state to switch to, for a given input.

What is a Mealy finite-state machine?

In the theory of computation, a Mealy machine is a finite-state machine whose output values are determined both by its current state and the current inputs. This is in contrast to a Moore machine, whose (Moore) output values are determined solely by its current state.

### What is the difference between Mealy machine and Moore machine?

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.

How do I know if my machine is Mealy or Moore?

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 are Mealy and Moore 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.

How do you know if its Moore or Mealy?

The key difference between Moore and Mealy is that in a Moore state machine, the outputs depend only on the current state, while in a Mealy state machine, the outputs can also be affected directly by the inputs.

### What are the functions of Moore and Mealy machines?

The value of the output function is a function of the current state and the changes at the clock edges, whenever state changes occur. 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.

What happens if the input is high in FSM?

What happens if the input is high in FSM? Explanation: The system changes the state as long the input is high. The system also has an output which is 1 if the input is high since there is a change in state which leads to the output.

## Is Mealy better than Moore?

Moore machines may be safer to use, because they change states on the clock edge (if you are using DFF logic for present and next state), whereas Mealy machines are faster, because the state is dependent on the input. Thus, the state can change asynchronously.

What is symbol in finite state machine?

Finite State Machine is defined formally as a 5‐tuple, (Q, Σ, T, q0, F) consisting of a finite set of states Q,a finite set of input symbols Σ, a transition function T: Q x Σ →Q, an initial state q0 ∈ Q, and final states F ⊆ Q . FSM can be described as a state transition diagram.
