In the following figure, output of AND gate is made as input of NOT gate, we get NAND gate <img class="img-fluid question-image" alt="image" src="https://cdn.tardigrade.in/img/question/physics/b73b6b2ec15ea2ea53415b0b7967fdfc-.png" /> Y = overline A ⋅ B

Q. What is the Boolean equation for the figure?

$Y = A + B$

$Y = \overline{A + B}$

$Y = \overline{A} + \overline{B}$

$Y = \overline{A \cdot B}$

In the following figure, output of $A N D$ gate is made as input of $NOT$ gate, we get $N A N D$ gate

$Y = \overline{A \cdot B}$

Q. What is the Boolean equation for the figure?

Y=A+B

Y=A+B​
