WebJul 28, 2013 · A "don't care" condition is a combination of inputs for which the designer doesn't care what the output is. Therefore "don't care" conditions can either be included in or excluded from any circled group, whichever makes it larger. They are usually indicated on the map with a dash or X. The example on the right is the same as the example above ... WebStep 5: Lastly, we find the boolean expression for the Output. To find the simplified boolean expression in the SOP form, we combine the product-terms of all individual groups. So the simplified expression of the above k-map is as follows: A'+AB'C'. Let's take some examples of 2-variable, 3-variable, 4-variable, and 5-variable K-map examples.
