QUESTION 3

Each "1" in a K-map square represents:

an input combination that results in a HIGH output.

an input combination that results in a LOW output.

an input combination that results in a DON'T CARE grouping.

None of the above.

10 points

QUESTION 4

Select the statement that best describes the use of "Don't Care" conditions on a K-map.

Don't Care conditions may only be changed to 1s.

Don't Care conditions should never occur and should not be included in K-map simplification procedures.

Don't Care conditions may only be changed to 0s.

Don't Care conditions may be changed to either a 0 or a 1.
