The circuit given below represents which of the logic operations?

Options

A. AND
B. NOT
C. OR
D. NOR

Answer

A

Explanation

Let two inputs are A and B. The circuit can be shown as :

Two gates shown in figure, are NAND gates.
The output of gate-1, `Y_(1)=bar(A*B)`
The output of gate-2, `Y=bar(Y_(1)*Y_(1))`
`or Y=bar(bar(A*B)*bar(A*B))=barbar(A*B)=A*B`
Thus, the combination behaves as it is an AND gate.
