7. Given that F = SUM m(0,2,4,6), which of the following correctly
describes F'?

- F' = PRD M(0,2,4,6)
- F' = PRD M(1,2,4,6)
- F' = PRD M(1,3,5,7)
- F' = SUM m(0,1,2,3)
- F' = SUM m(0,2,4,6)

1 is CORRECT. The truth table for F' has zeros in rows
0,2,4, and 6; therefore F' = PRD M(0,2,4,6). F' also may be
expressed in canonical SOP (minterm) form: F' = SUM
m(1,3,5,7); however, this expression does not appear as a
possible answer.
