Let after 1 textstNAND gate the result is Z. Z= overlineA ⋅ B 2 text nd NAND gate with common input behave like a NOT, result y= barZ= overline overlineA ⋅ B=A B

Q. The adjoining logic symbol is equivalent to

OR gate

AND gate

NOT gate

NAND gate

Let after $1^{st}$ NAND gate the result is $Z$ .
$Z = \overline{A \cdot B}$
$2^{nd}$ NAND gate with common input behave like a NOT, result $y = \overset{ˉ}{Z} = \overline{\overline{A \cdot B}} = A B$
