alleryStart learning →NAND gate truth table: output is 0 when:
AAll inputs 0
BALL inputs are 1 (NAND = NOT AND)
CAny input 0
DRandom
Answer & Solution
Correct answer: B. ALL inputs are 1 (NAND = NOT AND)
**NAND:** Y = (A · B)'.
Output = 0 only when all inputs = 1. Universal gate (any Boolean function can be built from NAND alone).
Similarly NOR is universal.
