## What is K-map in digital electronics?

A Karnaugh map (K-map) is a pictorial method used to minimize Boolean expressions without having to use Boolean algebra theorems and equation manipulations. A K-map can be thought of as a special version of a truth table . Using a K-map, expressions with two to four variables are easily minimized.

**How do you write a K-map?**

Transfer the 1s from the locations in the Truth table to the corresponding locations in the K-map.

- Group (circle) the two 1’s in the column under B=1.
- Group (circle) the two 1’s in the row right of A=1.
- Write product term for first group = B.
- Write product term for second group = A.

### What is K-map format?

The K-map method of solving the logical expressions is referred to as the graphical technique of simplifying Boolean expressions. K-maps are also referred to as 2D truth tables as each K-map is nothing but a different format of representing the values present in a one-dimensional truth table.

**What is K-map list its types?**

K-map can take two forms Sum of Product (SOP) and Product of Sum (POS) according to the need of problem. K-map is table like representation but it gives more information than TRUTH TABLE. We fill grid of K-map with 0’s and 1’s then solve it by making groups. Steps to solve expression using K-map-

#### Who has invented K-map?

Maurice Karnaugh

Maurice Karnaugh (/ˈkɑːrnɔː/; born 4 October 1924) is an American physicist, mathematician and inventor known for the Karnaugh map used in Boolean algebra.

**What is the other name of K-map?**

The Karnaugh map (KM or K-map) is a method of simplifying Boolean algebra expressions.

## Why Gray code is used in K-map?

In k-map the same simplification of Boolean expression is done by pairing adjacent 1’s for reducing variables. so if gray code is used in K-map the adjacent cells can be easily paired as they differ by only one bit and final expression can be obtained.
