    The given figure shows the waveforms for two inputs A and B and that for the output Y of a logic circuit. The logic circuit is

    A) AND gate           

    B) OR gate             

    C) NAND gate         

    D) NOT gate

    Correct Answer: A

    Solution :

    [a] From the given waveforms, the following truth table can be made________
    Time interval Input Output
    A B Y
    \[0\to {{T}_{1}}\] 0 0 0
    \[0\to {{T}_{2}}\] 0 1 0
    \[0\to {{T}_{3}}\] 1 0 0
    \[0\to {{T}_{4}}\] 1 1 1
    This truth table is equivalent to 'AND' gate.
