A) XOR
B) OR
C) AND
D) NAND
Correct Answer: D
Solution :
The given truth table gives 0 * 0 = 1 0 * 1 = 1 1 * 0 = 1 1 * 1 = 0 The above data represents the expression \[Y=\overline{A\,\,.\,\,B}\] This expression is the Boolean expression of NAND gate. Note: NAND gate used as OR function Thus \[\overline{A\cdot B}=\overline{A}+\overline{B}\] This is according to De Morgan?s theorem which states that complements of produces equals the sum or vice-versa.You need to login to perform this action.
