The younger brother wants to teach himself about electronics, but now he is just starting out and he

The basis of the circuit side is analog circuits, and digital circuits.

Generally, I look at analog circuits first, and then I am learning digital circuits.

Analog circuits are the basis of digital circuits, but in practical applications, I feel that I can only look at digital circuits, but when encountering more accurate calculations, analog circuits are still inseparable from analog circuits, and analog circuits are more difficult. After that, you can learn about signals and systems. These are the basics, and then you can apply them practically, in learning to learn the microcomputer, the next level is the microcomputer principle, and then the integrated circuit.

If it's just for maintenance, after learning digital analog circuits, you can learn single-chip microcomputer, I specialize in physics, and the nearby classmates are professional electronics.

To learn electronics, first of all, the mathematical ability must keep up, if it is no problem, it is to learn components first, the second is the combination of electrical engineering foundation and electronic technology foundation, three and then look at the digital circuit, and then to the special courses (such as the principle and maintenance of television, the principle and maintenance of DVD players, the maintenance of digital equipment, etc.), this is my three-year learning course, I hope to help you.

It is recommended to go to Xinhua Bookstore to order the annual "Electronic Newspaper", 40 yuan a year, two volumes a year. It talks about electronics, electronic technology, digital, computers, communications, etc. Very useful, I order it every year!

In order to learn electronic technology, for beginners, it is necessary to first learn electronic circuits. Master various electronic components and various unit circuits. Learn about diodes and transistors and their circuits.

Learn step by step, master the use and symbols of various components, and so on. At the same time, it is necessary to understand the basics of electricians.

1. Gradually familiarize yourself with the detection and use of commonly used electronic components, and gradually understand the principle and function of unit circuits with corresponding book knowledge.

2. To learn electronic technology knowledge, you have to have patience and perseverance. You have to be hands-on (e.g. using a universal board to lap some basic circuits.

3. "Fundamentals of Electrician" is also to be mastered, and books related to low-frequency circuits, high-frequency circuits, and digital circuits are all useful.

4. Constantly find problems in electronic technology. Ask questions (find out what you don't understand) and solve them.

The key to learning this book "Learning the Basics of Circuits from Scratch" is perseverance, patience and drilling.

The first step, start here, and ask later.

If you are young, go to technical school, and when you are older, you don't know so much.
