Karnaugh mapping is the preferred method to design logic circuits from an excitation diagram. Sum of product expressions can be formed directly from excitation tables. For J = X; K = X conditions:
A) do not form SOP expressions for X inputs.
B) X must be treated as a 0.
C) X must be treated as a 1.
D) any of the above

Question

Quizplus · Accepted Answer

In the context of Karnaugh maps and logic circuit design, an 'X' in J = X; K = X conditions can be treated as a don't care condition. This means it can be considered as 0, 1, or either, depending on what simplifies the logic expression the most. Therefore, any of the approaches mentioned can be correct depending on the specific optimization goal.
