Solved: PHYSICS Question for NEET

NEET PHYSICSEasy

Symbolic representation of four logic gates are shown. Pick out which ones are for AND, NAND and NOT gates, respectively.

(iii), (ii) and (i)

(iii), (ii) and (iv)

(ii), (iv) and (iii)

(ii), (iii) and (iv)

To identify the logic gates from their symbolic representations:

AND Gate: Represented by a 'D-shaped' symbol with two or more inputs and one output. In the typical figure sequence for this question, it is represented by (ii).
NAND Gate: Represented by an AND gate symbol with a small bubble (inversion circle) at the output. It corresponds to (iv).
NOT Gate: Represented by a triangular symbol with a small bubble at the output, having a single input and a single output. It corresponds to (iii). Therefore, the correct sequence for AND, NAND, and NOT gates respectively is (ii), (iv), and (iii).
