    The following figure shows a logic gate circuit with two inputs A and B and the output Y. The voltage waveforms of A, B and Y are as given                                                                                                                [AIPMT (M) 2010]
     The logic gate is

    A)  NOR gate        

    B)       OR gate           

    C)  AND gate    

    D)  NAND gate

    Correct Answer: D

    Solution :

    Table of logic gate
    A B Y
