    Hi,
    This was one of the questions asked to me during an interview. If anyone knows the answer, please reply.

    Which of the following can behave as a universal gate:

    1) Xnor + invertor
    2)And + or
    0

    I think you are alone in choosing option 2.

    definitely 2 nd option is correct..............
    because of these(OR and NOT)we will develop other gate i.e.NOR

    The NAND gate (inverted AND gate) is considering the universal gate because you can create any of the other logic circuits (OR, NOR, NOT, etc.) from it.

    I agree that you can make a NOR gate out of OR and NOT.

    Trouble is that the original post was this:


    Which of the following can behave as a universal gate:

    1) Xnor + invertor
    2)And + or
    Option 2 does not mention a NOT gate.

    Definitely 2nd option is wrong.

    Neither option can be used for a universal gate.
