    If the output of a 2-input NOR gate is fed as the input to a NOT gate (i) name the new logic gate obtained and (ii) write down its truth table.   
    Inputs Output of NOR Gate Output of NOT Gate
    A B \[\Upsilon '=\overline{A+B}\] \[\Upsilon =\overline{\Upsilon }'\]
    0 0 1 0
    0 1 0 1
    1 0 0 1
    1 1 0 1
     

    Answer:

                        As\[\Upsilon =A+B,\] so the new logic gate obtained is an OR gate.
