Question

The output waveform of the given logical circuit for the following inputs A and B as shown below is: Image

G1 Physics · Accepted Answer

The first two gates act as NOT gates for A and B, and the final NAND combination gives Y = A + B, i.e. OR operation. Applying OR to the given input waveforms produces the waveform shown in option 4.
