As far as I am concerned, this phrasing of your question is not sufficiently clear. In the context of what kind of input-output system are you asking this question? If it's a static arrangement of logic gates, then there can only be $\displaystyle 2^3=8$ different outputs anyway, and to bring them about, 5 different inputs are certainly sufficient.

But you could be taking about a more general kind of input-output automaton. - If so,*what*kind? - Feb 25th 2011, 05:36 PMAndyMan
thanks so much for the answer u posted to me. the question is about a circut bits.
