논리식 \(L = \overline{A}\,\overline{B} + \overline{A}B + AB\)를 간단히 하면?
- ① \(A + B\)
- ② \(A + \overline{B}\)
- ③ \(\overline{A} + \overline{B}\)
- ④ \(\overline{A} + B\) 정답
📖 해설
\(L=\overline{A}\overline{B}+\overline{A}B+AB = \overline{A}(\overline{B}+B)+AB = \overline{A}+AB\)
흡수법칙 \(\overline{A}+AB = \overline{A}+B\)를 적용하면 \(L=\)\(\overline{A}+B\)
흡수법칙 \(\overline{A}+AB = \overline{A}+B\)를 적용하면 \(L=\)\(\overline{A}+B\)
