Beginner Topic 9 of 51 Computer Architecture & Logic

Karnaugh Maps

Graphical method for minimizing Boolean expressions.

How it works

A K-map arranges a truth table in Gray-code order so adjacent cells differ in one variable; grouping adjacent 1s in rectangles of 1, 2, 4, 8… gives a minimal sum-of-products.

Where it is used

Hand-simplifying circuits of up to 4–5 variables.

Common pitfall

Missing larger groups or wrap-around edges, which yields non-minimal results.

Where it fits in the course

Karnaugh Maps is topic 9 of 51 in Computer Architecture & Logic, rated Beginner. It follows Boolean Algebra. The next topic is Combinational Circuits.
