Question
In K-map, you might find some cells filled with the letter d (or X). This d is called "Don't
care"
There may arise a case when for a given combination of input, we may not have a
specified output, or the input combination may be invalid. The combinations for which
we don't have any output expression specified are called don't care combination.
When forming groups of cells, don't care conditions (d) are considered as 1, if it helps
form the largest group, otherwise it is considered as 0 and are left during grouping.
This is helpful if it allows us to form a larger group than would otherwise be possible
without the don't cares. There is no requirement to group all or any of the don't cares.
Rule: Only use the Don't cares in a group if this simplifies the logic.
Based on the above note, and applying the same K-Map rules, you are asked to answer
the below questions for the below 4-variable K-Map:
a- Show the groups that should be considered, replacing the d's where necessary
to obtain the optimal solution. (You should replace only the needed d with 1 in
your solution and 0 otherwise).
b- Write the simplified equation of the function F.
c- Find the complement (F') of the simplified F. Apply De Morgan's law and show
the steps. You can keep it in the product of sum form.
