The map is topologically a torus; the edges "wrap around," meaning the leftmost cells are adjacent to the rightmost cells, and the top cells are adjacent to the bottom ones. How to Use a K-Map
cells. For example, a 2-variable map has 4 cells, while a 4-variable map has 16 cells. karnaugh map
The rows and columns are labeled using Gray code , where only one bit changes between adjacent cells (e.g., 00, 01, 11, 10). This property is critical because it ensures that cells appearing next to each other on the map differ by only one variable, allowing them to be combined to eliminate that variable.
