Identify the logic operation carried out by the following circuit.
1
AND
2
NAND
3
NOT
4
OR
Official Solution
Correct Option: (2)
- The circuit consists of two AND gates. The first AND gate takes inputs and , while the output of the first AND gate is passed to a NOT gate. The NOT gate inverts the output of the AND gate. - Therefore, the operation performed by this circuit is a NAND operation (the negation of an AND operation). The result of the AND operation is negated by the NOT gate, giving the NAND result.
