Physics - Semiconductors Question with Solution | TestHub

Given expression is

$\left(\overline{A+B}\right).\left(\overline{A.B}\right)$

Substitute$A=0$and$B=0$in above expression,

$=\left(\overline{0+0}\right).\left(\overline{0.0}\right)$

$=\overline{0}.\overline{ 0}=1. 1=1$

Hence, (0, 0) is the input of the given Boolean expression.
