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.

Exclusive nor gate logic
so it is even function of 1's... ??
