Identify the correct Logic Gate for the following output

(Y)

of two inputs A and B .

(A)(see structure)
(B)(see structure)
✓ Correct
(C)(see structure)
(D)(see structure)

Answer: (B)

Solution

From the truth table shown in the stem, when both inputs are 1, output is 0; for all other combinations (0,0), (0,1), (1,0), output is 1. This is the characteristic of a NAND gate:

Y = \overline{A \cdot B}
