This is made with NAND, AND and OR gate. Therefore Y= barA barB+AB

Q. For this truth table

Which logic expression is correct?

$Y = \overset{ˉ}{A} B + \overset{ˉ}{A B}$

$Y = \overset{ˉ}{A} \overset{ˉ}{B} + A \overset{ˉ}{B}$

$Y = \overset{ˉ}{A} \overset{ˉ}{B} + \overset{ˉ}{A B}$

$Y = \overset{ˉ}{A} \overset{ˉ}{B} + A B$

This is made with NAND, AND and OR gate.
Therefore $Y = \overset{ˉ}{A} \overset{ˉ}{B} + A B$

Q. For this truth table Which logic expression is correct?

Y=AˉB+ABˉ

Y=AˉBˉ+ABˉ
