B) NAND
C) AND
D) NOR
Show Answer
Answer:
Correct Answer: C
Solution:
- The truth table for the given circuit is
A | B | $ {{\mathbf{y}} _{\mathbf{1}}} $ | $ {{\mathbf{y}} _{\mathbf{2}}} $ | $ y=y_1+y_2 $ |
---|---|---|---|---|
0 | 0 | 1 | 1 | 0 |
0 | 1 | 1 | 0 | 0 |
1 | 0 | 0 | 1 | 0 |
1 | 1 | 0 | 0 | 1 |
The truth table shows that both the inputs are high, then we are getting high value of output otherwise zero. Hence, the combination represents AND gate.
