用卡诺图化简法化简下列逻辑函数 F(A,B,C,D)=∑(m0,m1,m3,m4,m6,m7,m1

用卡诺图化简法化简下列逻辑函数 F(A,B,C,D)=∑(m0,m1,m3,m4,m6,m7,m14,m15)+∑d(m8,m9,m11,m12)

Answer 1

F(A,B,C,D)=∑m(0,1,3,4,6,7,14,15)+∑d(8,9,11,12)

如下图，绿色和橙色的圈二选其一就行，2个答案都对

=BC+CD+C'D'   +B'C'(应对三个红的+橙的)

=BC+CD+C'D'   +B'D (应对三个红的+绿的)

Answer 2

引用boysoft的回答：
F(A,B,C,D)=∑m(0,1,3,4,6,7,14,15)+∑d(8,9,11,12)
如下图，绿色和橙色的圈二选其一就行，2个答案都对
=BC+CD+C'D' +B'C'(应对三个红的+橙的)
=BC+CD+C'D' +B'D (应对三个红的+绿的)

答案有错啊，这个卡诺图用三个圈就可以圈了啊，答案应该是CD+BD'+B'C'
