Possible Questions on Logic Gates in NEET Exam

Introduction:

NEET is an all-India medical entrance exam that tests the aptitude of students who aspire to join medical or dental courses in India. The exam comprises multiple-choice questions from various subjects, including physics, chemistry, biology, and mathematics.

Logic Gates in NEET Exam:

Logic gates are fundamental building blocks of digital electronics. These are electronic circuits that perform logical operations on one or more inputs to produce an output. In NEET exam, logic gates may be included in the physics or the mathematics section.

Possible Questions:

1. Identify the logic gate represented by the following symbol:


(a) OR gate
(b) AND gate
(c) NOT gate
(d) XOR gate

2. What is the output of the following logic circuit when input A=1 and input B=0?


(a) 0
(b) 1
(c) NAND gate
(d) NOR gate

3. How many logic gates are required to implement the following Boolean expression using AND and OR gates?

F = AB + CD

(a) 2
(b) 3
(c) 4
(d) 5

4. Which of the following is a universal gate?

(a) AND gate
(b) OR gate
(c) NOT gate
(d) NAND gate

Conclusion:

NEET exam may include questions on logic gates from the physics or mathematics section. Students should be familiar with the symbols, truth tables, and Boolean expressions of logic gates to answer these questions confidently.
