    The following figure shows a logic gate circuit with two inputs A and B and the output C. The voltage waveforms of A, B and C are as shown below:                                                                                      [AIPMT (S) 2006]
               
    The logic circuit gate is:

    A)  AND gate                     

    B)  NAND gate      

    C)  NOR gate

    D)                   OR gate

    Correct Answer: A

    Solution :

    The Boolean expression which satisfies the output of this logic gate is \[C=A\]. B, which is for AND gate.
