Q. A truth table is given below. Which of the following has this type of truth table [table] A | 0 | 1 | 0 | 1 ; B | 0 | 0 | 1 | 1 ; y | 1 | 0 | 0 | 0 [/table]
A) XOR gate
B) NOR gate
C) AND gate
D) OR gate
Explanation
(b) In ‘NOR’ gate $Y = \overline{A + B}$
$i.e.,\ \overline{0 + 0} = \overline{0} = 1,\ \overline{1 + 0} = \overline{1} = 0$
$\overline{0 + 1} = \overline{1} = 0,\ \overline{1 + 1} = \overline{1} = 0$
