UGC Net Computer Science Paper II Dec 12

1. Consider the circuit shown below. In a certain steady state, Y is at logical ‘l’.What are possible values of A, B, C ?
(A) A = 0, B = 0, C = 1
(B) A = 0, B = C = 1
(C) A = 1, B = C = 0
(D) A = B = 1, C = 1
Flip-flop UGC Net Computer Science Paper II Dec 12

Answer A
Explanation : Nand gate behave opposite of and gate so if any 0 in input then result will be 1. So output Y will be 1 if A = 0, B = 0, C = 1
