Which rows does POS use?
Short answer. Rows where F = 0.
What does Σ mean here?
Sum of minterms.
F is 1 in rows 1, 2
| Form | Uses | Result |
|---|---|---|
| SOP | rows F = 1 | Σ(1,2) |
| POS | rows F = 0 | Π(0,3) |
Remember
| SOP: minterms of 1s |
| POS: maxterms of 0s |
Same truth table, two canonical forms. Which rows go where? Here F is one in rows one and two. SOP adds minterms where F is one. POS multiplies maxterms where F is zero. Two rules. SOP uses ones. POS uses zeros.
