Which of the following gives output 0 in the NAND gate?
Options
- AA = 1 , B = 0
- BA = 1 , B = 1
- CA = 0 , B = 0
- DA = 0 , B = 1
Correct answer
B. A = 1 , B = 1
Step-by-step solution
The Boolean expression for a NAND gate is Y = A B . For A = 1 , B = 0 , Y = 1 0 = 0 = 1 For A = 1 , B = 1 , Y = 1 1 = 1 = 0 For A = 0 , B = 0 , Y = 0 0 = 0 = 1 For A = 0 , B = 1 , Y = 0 1 = 0 = 1 The output is 0 when A = 1 and B = 1 . Answer: A = 1 , B = 1
