Notation for incompletely specified functions
Don't cares and canonical forms
- so far, only represented on-set
- also represent don't-care-set
- need two of the three sets (on-set, off-set, dc-set)
Canonical representations of the BCD increment by 1 function:
Z = m0 + m2 + m4 + m6 + m8 + d10 + d11 + d12 + d13 + d14 + d15 Z = ? [ m(0,2,4,6,8) + d(10,11,12,13,14,15) ] Z = M1 � M3 � M5 � M7 � M9 � D10 � D11 � D12 � D13 � D14 � D15 Z = ? [ M(1,3,5,7,9) � D(10,11,12,13,14,15) ]
