Yes crutschow, i have read that paper and my idea is based on that paper too, but i dont want a specific circuit, since this is a theoretically approach i want a general circuit, Do u know what i mean? I dont want to write these gates in matlab and then try to combined them for a particular logic problem and get a sequential circuits, whereas i can use some kind of algorithm step to make such fuzzy circuits or used traditional way to build circuits.So that i could defined these on the paper, it could be theoretical only and that works too.
