Question

The simplified form of Boolean expression
$\overline{(a+\overline{b}+c+\overline{d})+(b+\overline{c})}$
is

• A. 1
• B. $\overline{a.b}$
• C. 0
• D. a, b

Answer 1

The correct option is C 0

F = $\overline{(a+\overline{b}+c+\overline{d})+(b+\overline{c})}$
= $\overline{(a+\overline{b}+c+\overline{d}}$. $\overline{(b+\overline{c})}$
= $\overline{a}.b.\overline{c}.d.\overline{b}.c$
F = 0
