① Search on the some circuits using Mealy machine and Moore machine.
- Mealy Machine
Present state and input determine output. Therefore, Output is different depend on present state. So This machine have high degree of freedom. But input signal deliver to output device directly. So input noise can influence to output.
For example, Let think of system of door lock. It have secret number for open. It is `1234`. we have two different try. Both of them have `123`. But first one have ``1234`. So output is open. Seconde one is `1230` So output is lock. It is example of Mealy Machine that have another output depend on input and present state. Another example is cell phone and mouse, etc.
- Moore Machine
Present state determine output. Therefore, one state hold only one output. So it have more state than Mealy Machine. But Moore Machine have some benefit compare to Mealy Machine. Noise can`t influence to Moore Machine.
