Don't Care Condition:

In digital circuits, many times some input combinations are never used. The output for these unused input combinations is un-specified. (e.g in 8421 BCD code, the six combinations are invalid codes ). Such input combinations are known as don't care combinations and in the K-map, such don't care terms are defined by either X or d. In the K-map, these don't care terms can be used for the minimization of the Boolean Function.

In this video, through the different examples, it has been explained that how to use the don't care condition in the K-map for the minimization of the Boolean Function.
