To answer this question, you need to understand the purpose and applications of Karnaugh maps (K-maps).
Karnaugh maps are a graphical method used in digital logic design to simplify Boolean expressions. Boolean expressions are mathematical expressions that represent the logic of a digital circuit. They are composed of variables, logical operators (such as AND, OR, and NOT), and constants (0 or 1).
K-maps provide a systematic approach for simplifying Boolean expressions by visually representing the truth table of a given logic function. The K-map technique allows for the identification and grouping of adjacent 1s in the truth table, which can be combined to form simplified Boolean expressions. This simplification process results in a reduced number of logic gates required to implement the function, leading to more efficient and cost-effective circuit designs.
Therefore, the correct answer is B) Boolean expressions. The Karnaugh map technique provides a systematic method for simplifying Boolean expressions.
