Which one of the following is the Boolean expression of the NAND gate?
Correct answer: C. X = Ā.B̄
- A. X = A.B
- B. B X = A + B
- C. X = Ā.B̄
- D. X = Ā + B̄
Explanation
The Boolean expression given for a NAND gate is that of logical addition and it is opposite to the AND gate The Boolean algebra for AND gate is X=A.B So, the Boolean algebra for the NAND gate is: X=A.B

About Electrical Properties of Solids
Electrical properties of solids depend on their band structure, charge carriers and conductivity. The topic compares conductors, insulators and semiconductors, relates resistivity to temperature, and covers intrinsic and extrinsic semiconductors, donor and acceptor impurities, electron and hole conduction, and the formation of p-type and n-type materials.
