How many rows in the NAND gate truth table produce output 0?
Explanation
Only one row (A=1 B=1) produces output 0 in a 2-input NAND gate truth table. All other combinations produce output 1.
Reference: Computer Studies Textbook , Page 6
Hint
NAND is the complement of AND — AND has one row with output 1 so NAND has one row with output 0.
