  • question_answer
    To get an output \[Y=1\] in given circuit which of the following input will be correct                 [AIPMT (M) 2012]
                            A          B          C

    A) 1          0          0

    B) 1          0          1

    C)             1          1          0

    D)             0          1          0

    Correct Answer: B

    Solution :

    Here \[Y=(A+B)\cdot C\]
    Truth Table
    A B C \[Y=\left( A+B \right).C\]
    0 1 0 0 0 1 1 0 0 1 1 1 0 1 0 0 0 0 1 1 1 0 0 0 0 1 1 1
    C should be 1 either A and B or both A and B are 1
