Advantages and disadvantages of Mealy and Moore?  

well, the outputs are properties of states themselves... which means that you get the output after the machine reaches a particular state, or to get some output your machine has to be taken to a state which provides you the output. you can have each counting state assigned an output which enables the counter dedicated to the candidate (moore machine).


The outputs are held until you go to some other state

Mealy machine:
Mealy machines give you outputs instantly, that is immediately upon receiving input, but the output is not held after that clock cycle.

Adv & Disadv:
In Mealy as the output variable is a function both input and state, changes of state of the state variables will be delayed with respect to changes of signal level in the input variables, there are possibilities of glitches appearing in the output variables.
Moore overcomes glitches as output dependent on only states and not the input signal level.

Mealy machine: machines having outputs associated with transition (input and the current state).

Moore machine: machines having outputs associated with states.

All of the concepts can be applied to Moore-model state machines because any Moore state machine can be implemented as a Mealy state machine, although the converse is not true.
