Question 114: Semiconductors and Logic Gates

Question

Which one of the following will be the output of the given circuit?

Accepted Answer

$$y = \left( {\overline {A.B} } \right)\,.\,\left( {A + B} \right)$$
$$ = \left( {\overline A  + \overline B } \right)\,.\,\left( {A + B} \right)$$
$$ = \overline A \,A + \overline A \,B + A\,\overline B  + \overline B \,B$$
$$ = 0 + \overline A \,B + A\,\overline B  + 0$$
$$y = \overline A \,B + A\,\overline B $$
