    The output of a NAND gate is 0                            [UPSEAT 2004]

    A)            If both inputs are 0            

    B)            If one input is 0 and the other input is 1

    C)            If both inputs are 1            

    D)            Either if both inputs are 1 or if one of the inputs is 1 and the other 0

    Correct Answer: C

    Solution :

                       If inputs are A and B then output for NAND gate is \[Y=\overline{AB}\]                    Þ If \[A=B=1\], \[Y=\overline{1.1}=\bar{1}=0\]
