    Pretty straightforward if you think about it.
    What kind of gate does XNOR represent ?

    for 3 input variables, xnor logic is 'even function of 0's'.. and in some books it is written 'even func. Of 1's'.. don't know why is that so? Any explanation please :-|

    XNOR is the opposite of XOR gate.
    Have a read of this: XNOR gate - Wikitronics
    Sufficed to say XNOR with 3+ inputs behaves erratically.
