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 had never seen one, but found this. http://answers.yahoo.com/question/index?qid=20120124234255AA9fbB2
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.
