A NAND gate is called a universal logic element because______________?
Correct answer: B. any logic function can be realized by NAND gates alone
- A. it is used by everybody
- B. any logic function can be realized by NAND gates alone
- C. all the minization techniques are applicable for optimum NAND gate realization
- D. many digital computers use NAND gates
Explanation
NAND gates are universal because they can first be combined to produce NOT, AND, and OR operations, from which any Boolean logic function can be constructed. The other choices describe usage or implementation issues, not universality.
