    When using nor gates only do I use the SOP, double bar it, and then change all the ands to an or? Or do i use the pos and double bar that then use demorgans?

    my first attempt was,
    F=A'BC'D' + A'B'C'D + ABC + AB'C --> need to use nor gates only for this

    F = (A + B' + C + D' + A + A' + B' + D + A' + B + C)'

    it looks weird to me =/
    you cant simply if the whole thing is bar, can you?

    any help would be appreciated
    thanks
