Digital input signals A, B, C with A as the MSB and C as the LSB are used to realize the Boolean function F = m0 + m2 + m3 + m5 + m7, where mi denotes the ith minterm. In addition, F has a don’t care for m1. The simplified expression for F is given by:
1
\(\bar A\bar C + \bar BC + AC\)
2
\(\bar A + C\)
3
\(\bar C + A\)
4
\(\bar AC + BC + A\bar C\)
