0 | 0 | 1 |
A) NAND gate
B) XOR gate
C) NOR gate
D) OR gate
Correct Answer: A
Solution :
The given truth table is for NAND gate. The output for NAND gate is 1 only when one of its inputs is zero. The Boolean expression for NAND gate is \[Y=\overline{A\,.\,B}\] That is \[\overline{1\,.1}=\bar{1}=0\] \[\overline{0\,.1}=\bar{0}=1\] \[\overline{1\,.0}=\bar{0}=1\] \[\overline{0\,.0}=\bar{0}=1\] Note: The symbol for NAND gate can be shown as:You need to login to perform this action.
