XNOR gate

  1. Oct 19, 2004 #1
    This question really doesn't make much sense to me.
    We will be creating the XNOR gate by cascading the output of the XOR gate, into the input of a NOT gate. The output from the NOT gate would then be the same as that from an (fill in the blank) gate.
    Does XNOR go in the blank? Or did I misunderstand the question?

    What do the truth tables look like?

    XNOR sounds right to me, the truth table should be

    A B Y
    0 0 1
    0 1 0
    1 0 0
    1 1 1

    Seems a little odd to me: maybe it's a NXOR or

    \overline {XOR}

    X (XOR) Y = X'Y+XY'

    they prolly what you to replace the XOR with inverters, ANDs, ORs

    I'm taking Logic design right now so i'll prolly be posting some more questions up here
