    The following figure shown a logic gate circuit with two inputs A and B and output C. The voltage waveforms of A, B and C are as shown in second figure below. The logic circuit gate is:

    A)  OR gate              

    B)  AND gate

    C)  NAND gate      

    D)  NOR gate       

    Correct Answer: B

    Solution :

    From the given input and output waveforms, the truth table can be constructed as given
    A        B        C
    0 0 0
    1         1         1
    0         1         0
    1 0 0
    The logic circuit is therefore, an AND gate, he
