  • question_answer 16)
    Write the truth table for a NAND gate connected as given in Fig. Hence identify the exact logic operation carried out by these circuits.  

    Answer:

    The NAND gate shown in the truth table has only one input. Therefore, the truth table is
    A A
    0 0 1
    1 1 0
    Since  in this case, the circuit is actually a NOT gate with the truth table
    A Y
    0 1
    1 0
