Introduction of three basic logical operators

This article gives you an introduction to the three basic logical operators. There is a certain reference value, friends in need can refer to, hope to help you.

Logic algebra has three basic logical operations: and, OR, and non. It is an algebra that operates according to a certain logical relationship, and is a mathematical tool used to analyze and design digital circuits. In addition, the logic and operation of logical variables are called and terms, and the logic or operations of items constitute the sum or of logical functions, also known as the sum of products.

There are three most basic logical operations:

1) Logic and-- expressed by AB: when both An and B are 1, the value is 1, otherwise it is zero.

2) logical OR-- denoted by Amarb: when both An and B are 0, the value is 0, otherwise it is 1

3) logical non-denoted by the word 'inverse' on A. when An is 0, the non-of An is 1 and the non-of An is 0.

Extended data:

By using the basic formulas and rules of logic algebra, the logic function can be transformed and the simplest form of expression can be obtained. The so-called simplest form here refers to the simplest and OR or the simplest or and. There are two criteria for judging them: the number of items is the least; under the condition of the least number of items, the text in the item is the least.

Karnaugh map is formed according to certain rules. Because of these laws, many characteristics of logical algebra are vividly and intuitively reflected in the graph, which makes it a powerful tool for formula proof and function simplification.

The above is a brief introduction to the three basic logical operators, of course, the detailed use of the above differences still have to be used by everyone to understand. If you want to know more, welcome to follow the industry information channel!
