    hey dear all...
    why do we use Gray code to set up our equations? Why Gray code can be easier to simplify Boolean equation?

    i don't think assigning gray code to fsm states produces simpler boolean equations . but gray codes r used because they will usually prevent cycles from happening cuz only one var in the state designation changes at a time .

    r u talking abt gray codes in K maps ?
    in that case , well actually K maps provide a graphical view of minterms or maxterms,these which differ by one var are grouped in consecutive rows or columns and thus can be combined(var and its complement x+x'=1)
