The output of the combination of the gates shown in fig is
Applying the logic of NAND and OR gates properly the output can be seen as A+¯¯¯¯¯¯¯¯¯¯¯¯A.B.
Input waveforms A and B as shown in figure are applied to the combination of gates as shown in fig. Which of the waveforms shown in (a,b,c,d) correctly represents the output waveform?
