     Sketch the output waveform obtained from NOR gate for the inputs A and B as shown in the figure.
     
      Input waveform of A and B
    .                             

    Answer:

                Truth table for NOR gate is

    A B \[\mathbf{Y=}\overline{\mathbf{A+B}}\]
    0 0 1
    0 1 0
    1 0 0
    1 1 0
    The output (Y) waveform obtained from NOR gate is shown in the figure.
