For the logic circuit shown, the output waveform at Y is: Image

Question

G1 Physics · Accepted Answer

Determine the output of each logic gate successively from the input waveform shown in the figure. After applying the Boolean operation of the first stage and then the final gate, the output is HIGH and LOW over the intervals exactly as shown in waveform 2. Therefore the output waveform is Image 2. Hence option B follows.
