 Bangaram said: (Mar 10, 2011) Output equation for the two input(A,B) exclusive-NOR gate is (A.B)+(A bar.B bar)... substitute input values...

 Sandeep Mandal said: (Mar 17, 2011) We know that in ex-nor gate same input is 1 and different input is 0. So clearly c is a right answer.

 Bijendra Kumar said: (Jul 28, 2011) In ex-nor gate if both terminal high or low then it gives high output other wise it gives low out put.

 Ganga said: (Mar 7, 2012) For exclusive-nor if both the inputs are same then only the output is 1.
