Show Answer
Answer:
Correct Answer: 13.(d)
Solution:
- (d) (a) is a NAND gate so output is $\overline{1 \times 1}=\overline{1}=0$
(b) is a NOR gate so output is $\overline{0+1}=\overline{1}=0$
(c) is a NAND gate so output is $\overline{0 \times 1}=\overline{0}=1$
(d) is a XOR gate so output is $0 \oplus 0=0$
Following is NAND Gate
$Y=\overline{A . B}$
