Semiconducting Devices Question 86
Question: The truth-table given below is for which gate
| A | 0 | 0 | 1 | 1 |
| B | 0 | 1 | 0 | 1 |
| C | 1 | 1 | 1 | 0 |
[CBSE PMT 1994, 98 2002; DPMT 2002; BCECE 2005]
Options:
A) XOR
B) OR
C) AND
D) NAND
Show Answer
Answer:
Correct Answer: D
Solution:
For NAND gate $ C=\overline{A.B} $ i.e.
$ \overline{0.0}=\bar{0}=1 $ , $ \overline{0.1}=\bar{0}=1 $
$ \overline{1.0}=\bar{0}=1 $ , $ \overline{1.1}=\bar{1}=0 $
