2024 · Q153

NEETPhysicsSemiconductor ElectronicsMCQ+4 / −1

A logic circuit provides the output YYY as per the following truth table :

NEET 2024 Physics - Semiconductor Electronics Question 7 English

The expression of the output Y is :

  1. A
    A⋅B+AˉA \cdot B+\bar{A}A⋅B+Aˉ
  2. B
    A⋅Bˉ+AˉA \cdot \bar{B}+\bar{A}A⋅Bˉ+Aˉ
  3. C
    Bˉ\bar{B}Bˉ
  4. D
    B

Correct answer: C

NEET 2024 Physics - Semiconductor Electronics Question 7 English Explanation

According to given truth table, output is independent on value of $A$

$\therefore$ Output $Y=\bar{B}$
