Why do the four corners form a group?
Short answer. The map wraps top to bottom and left to right.
What group sizes are allowed?
1, 2, 4, 8 or 16.
Σ(0,2,5,7,8,10,13,15)
| Group | Boxes | Term |
|---|---|---|
| Centre quad | 5, 7, 13, 15 | B.D |
| Corner quad | 0, 2, 8, 10 | B'.D' |
Remember
| Groups: 1, 2, 4, 8, 16 |
| Largest groups, fewest groups |
Eight minterms. Can a K-map make it two terms? Yes. The centre quad keeps B and D as one. The corners wrap into a quad with B and D zero. Two rules. Powers of two only. Largest and fewest groups.
