What is Karnaugh map and why is it used?

A Karnaugh map (K-map) is a graphical method used to simplify Boolean functions and expressions. It is a two-dimensional grid where each cell represents a combination of input variables and the corresponding output of the Boolean function. By grouping adjacent cells with the same output, the K-map helps identify patterns that can be combined, reducing the complexity of the Boolean function. This simplification process makes it easier to design digital circuits with fewer gates, reducing cost, size, and power consumption.
