[1998]

(A)

(C)

(B)

(D)

(a) $D$

(b) $A$

(c) $B$

(d) $C$

Show Answer

Answer:

Correct Answer: 110. (d)

Solution:

  1. (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

$Y=\overline{A . B}$
