In the digital circuit shown in the original figure, for the given inputs the values of P and Q are:

Question

G1 Physics · Accepted Answer

Evaluate the logic gates successively using the two input values shown in the original circuit. Following the signal through the first-stage gates gives the intermediate outputs shown in the source solution. Substituting those outputs into the final-stage gates gives P = 0 and Q = 0. Therefore the correct pair is (P,Q) = (0,0). Correct option: B.
