Example of a Mealy Finite State Machine

A Mealy finite state machine is a mathematical model used to describe the behavior of a sequential circuit. It consists of a set of states, a set of inputs, a set of outputs, and a set of transition functions that specify how the machine moves from one state to another based on the current state and input.

M Meaning of Each Row and Column

Let’s break down the transition table to understand its meaning. The table has four columns: Input, Current State, Next State, and Output.

– The Input column specifies the input to the machine for a particular state transition.
– The Current State column indicates the current state of the machine before the transition.
– The Next State column shows the next state of the machine after the transition.
– The Output column represents the output of the machine for a particular state transition.

Detailed Description of the Mealy Finite State Machine

Based on the transition table, we can describe the Mealy finite state machine as follows:

The machine starts in state A. When the input is 0, the machine remains in state A and outputs 0. When the input is 1, the machine moves to state B and outputs 1. In state B, when the input is 0, the machine remains in state B and outputs 1. When the input is 1, the machine moves back to state A and outputs 0.

This Mealy finite state machine can be used to model a simple sequential circuit that responds to input signals with output signals.
