GATE Question of The Day - Digital Electronics


 For the output F to be 1 in the logic circuit shown, the input combination should be?





 (A)        A = 1, B= 1. C = 0                                 (B)        A = 1, B= 0,C = 0
 (C)        A = 0, B= 1. C = 0                                 (D)        A = 0, B= 0, C = 1

I hope i am giving you the very simple questions! will see how many comments will hit to this post!

    as we exnor is an equivalence or coincidence logic ckt.for out to be "1", its all input should be equal .. but here to make output F =1 , C=A(EXOR)B=A(EXNOR)B.. now please say , how can you answer"d"...
