(9)Z =B(A+D)+( AD )
=B(A+D)+(A+D) =A+D=A D
=A(C+D)+AF+BD+BE+BF =AC+AD+F(A+B)+BE+BD =AC+AD+AF+BF+BD+BE
(2)Z =(A+BC)D =·(+)+C+ Z' =A·(B+C)++D
(10)Z =AC+AD+AF+B(D E)+BD+BE+BF
1.27 求反函数和对偶函数Z' (1)Z =AB+C =(+)· Z' =(A+B)·C
(3)Z =( C)(A+)AC BC =( )·(+) Z' =( A C)·(B+C) (4)Z =A+AC BCD+C
=(+D)· ·( )· Z' =(A+)·A C·(B C+D)·C (5)Z=(AC+BD)
=(+)·(+)+( B ) (C ) Z' =(A+C)·(B+D)+(A C) ( D) 1.28 用填卡诺图方法写最小项表达式 (1)F1=BC+AC+C = m(1, 3, 5, 7)
=+BC+AC+ABC
