Semiconductor Electronics question

2015 · Q132

NEETPhysicsSemiconductor ElectronicsMCQ+4 / −1
Which logic gate is represented by the following combination of logic gates ?

AIPMT 2015 Cancelled Paper Physics - Semiconductor Electronics Question 102 English
  1. A
    AND
  2. B
    NOR
  3. C
    OR
  4. D
    NAND
View written solutionFree

Correct answer: A

The Boolean expression of this arrangement is

Y = A‾+B‾‾\overline {\overline A + \overline B } A+B​ = A‾‾+B‾‾\overline{\overline A} + \overline{\overline B} A+B = A.B

Thus, the combination represents AND gate.
