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) ]
