AIPMT MAINS 2012 Physics Logic Gates MCQ Question
Type: MCQ-conceptual-Medium-Class 12
To get an output Y = 1 in given circuit which of the following input will be correct:
A
1 0 0
B
1 0 1
C
1 1 0
D
0 1 0
Correct Answer
Option B
Detailed Explanation
The circuit consists of an OR gate followed by an AND gate. For Y = 1, the OR gate must output 1, which happens when A = 1 or B = 1. The AND gate will output 1 when both its inputs are 1. Thus, when A = 1, B = 0, C = 1, the output Y = 1.
