What are don't care conditions, and how are they used in a Karnaugh map?
Original Khojo Papers practice question — not from a past board paper.
Answer
Don't care conditions are input combinations that either cannot occur or whose output does not matter. On a Karnaugh map they are marked with an X and may be treated as either 0 or 1, whichever helps to form a larger group, which usually gives a simpler expression.
No citable source has been recorded for this record. Treat it as practice material, not as fact.
Explanation
A don't care need not be covered at all if it does not help.
