Which one of the following is the truth table of the NAND gate?
Correct answer: B. Option B
- A. Option A
- B. Option B
- C. Option C
- D. Option D
Explanation
The NAND gate, or "NotAND" gate, is the combination of two basic logic gates, the AND gate, and the NOT gate, connected in series. The output of a NAND gate is high when either of the inputs is high or if both inputs are low. In other words, the output is always high and goes low only when both inputs are high. The logic NAND function is given by the Boolean expression X=A.B. The truth table of a NAND gate is given below

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.
