    In a negative logic the following wave form corresponds to the

    A)            0000000000                           

    B)            0101101000

    C)            1111111111                           

    D)            1010010111

    Correct Answer: D

    Solution :

               5 volt is low signal (0) and 10 volt is high signal (1) and taking 5 m-sec as 1 unit. In a negative logic, low signal (0) gives high output (1) and high signal (1) gives low output (0). The output is therefore 1010010111.
