Which of the following gates will have an output of 1 ? (a) Figure
(b)Figure
(c)Figure
(d)Figure

  • A
    $\mathrm{D}$
  • B
    $\mathrm{A}$
  • C
    $\mathrm{B}$
  • Correct answer
    D
    $\mathrm{C}$

Solution

(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 $0 \oplus 0=0$

Hence, the correct answer is option: 'D'.
