Is XNOR Gate Logic Correct for More Than 2 Inputs?

[fcbarcelona]

hi,,
i m a bit confused in XNOR gate logic for MORE THAN 2 INPUTS..
is this logic correct "even function of 0's"..
need help in this regard,thanks in advance..

I don't think they found the right answer there.

The generalization of an XOR gate is the Parity - it is 1 if there is an odd number of "1" inputs.
XNOR is an inversed XOR - it is 1 if there is an even number of "1" inputs.

It can be written as NOT(A XOR B XOR C XOR D) - and as interesting feature, the order of operations (and inputs) does not matter.

so it is even function of 1's... ??
