<img class="img-fluid question-image" alt="Solution" src="https://cdn.tardigrade.in/q/nta/p-scyakmxxrr93ho99.jpg" /> The above circuit is the combination of OR gate, NAND gate, and AND gate. So, the net output voltage is Y=(.A+B.)⋅ (. barA . B.) =(.A+B.)⋅ (. barA+ barB.) Y=A⋅ barB+ barA⋅ B(.XOR.)

Q. The following configuration of gates is equivalent to:-

$N A N D$

$OR$

$XOR$

$NOR$

The above circuit is the combination of $OR$ gate, $N A N D$ gate, and $A N D$ gate. So, the net output voltage is
$Y = (A + B) \cdot (\overset{ˉ}{A . B})$
$= (A + B) \cdot (\overset{ˉ}{A} + \overset{ˉ}{B})$
$Y = A \cdot \overset{ˉ}{B} + \overset{ˉ}{A} \cdot B (XOR)$
