I have come up with a problem which wants to convert a Mealy machine to a Moore machine. I searched the web and found out how to convert a Mealy machine to Moore machine and vice versa, but I have other questions which I couldn't find them on the web: 

 - What is the meaning of equivalence between Moore and Mealy machine? As you know The output of Mealy machine depends on the inputs when the input changes the output changes but Moore machine is not.

 - Why the conversion from Mealy to Moore is in the way described in this [link][1]?
