Karnaugh Maps

Karnaugh maps, also known as K-maps, are a graphical method used to simplify Boolean algebra expressions. They provide a systematic way to minimize Boolean functions and are particularly useful for simplifying expressions with up to five variables.

Karnaugh maps represent Boolean functions graphically in a tabular form. Each cell in the table corresponds to a unique combination of input variables.

The main technique used with Karnaugh maps is grouping adjacent cells with the value 1 to identify patterns that can be combined to simplify the expression.

Karnaugh maps are widely used in digital logic design, especially in the design of combinational logic circuits. They help engineers optimize circuits for speed, area, and power consumption.

Karnaugh maps provide a visual and systematic approach to simplifying Boolean expressions, making them an essential tool in digital logic design.

Maxterms

The maxterm numbers specify the positions of zeros in the truth table. Each maxterm number corresponds to the decimal equivalent of the binary expression on the left side of the truth table. For example, let's consider a 3-variable function with maximum terms of 0, 3, and 6. The binary equivalents of 0, 3, and 6 are respectively 000, 011, and 110. This tells us that in the truth table, the rows corresponding to 000, 011, and 110 have a value of 0, while others have a value of 1.

Obtaining the Karnaugh Map from the Maxterms

Each square on the Karnaugh map has a number. This number, like in maximum terms, indicates the position of the value in the truth table. Before starting the solution, we leave the corresponding place on the Karnaugh map blank for each maximum term and write 1s in the remaining places.

Product of Sums Output

When the 0's in the Karnaugh map are grouped in rectangular regions with sidelengths of 1, 2 or 4, the result is obtained in the form of the product of sums. This calculation tool provides the result in the form of the product of sums.

INPUT FORMAT

Enter the maxterms separated by commas or spaces.
