4-Variable K-Map

Previous post, you learned about 3-variable K-map, and learned how to minimize a boolean function. In this post, you will learn about bigger map such as a 4-variable K-map. With 4-variable map you will be able to make larger groups of cells. Plotting a 4-variable K-map The 4 variables of a boolean function will give …

3-Variable K-Map

The K-map or Karnaugh map is a graphical tool to minimize a boolean function. From the previous article, you know how a boolean function represented in canonical sum of product is changed into sum of product form using K-map. Also, the k-map is nothing but the same truth table in a matrix form where each …

Logic Gates

In this lesson, you will learn about -logic gates. The logic gates are building blocks of digital circuit to which voltage and current are applied to as binary logic 0 or 1. Voltage or current applied to analog circuits such as telephone systems as analog signals with continuous range from 0 to 5 V. A …

Binary-Coded Decimal

In the previous lesson, we learned about binary codes and how they are used for representing a distinct discrete element of information using 1s and 0s. People use the decimal system for everything and it’s easier for them to use decimal numbers on a computer than binary numbers. But binary is what the computer understands. …

Binary Codes

Binary codes are used to represent the distinct discrete element of information. They are patterns of 1s and 0s for a computer to understand information other than binary numbers. The discrete elements of information are not only binary numbers but also, other types of information such as decimal numbers, etc. Binary Code Suppose we have …

Complements

In the previous lesson, we learned about number systems – binary, decimal, octal and hexadecimal number systems in detail. Complements are very helpful in performing subtraction and save computing time and lead to simple circuits. Before we move to subtraction, let’s understand what complement is all about. In simple words, if there is group with …
