1. How to learn electronic technology is a big problem. Solving this problem is a systematic project. It takes time first. Secondly, it is necessary to read more books and practice more. Twinkle System Technology Co Ltd , https://www.pickingbylight.com
Learning this subject at least includes the following three aspects. These three skills are indispensable and affect each other. They are an inseparable whole.
(1) Master the working principle of the circuit, that is, to understand the circuit diagram.
(2) Understand the theory and inspection methods of fault analysis, that is, in the face of the changing phenomena of change, you can have a "spectrum" in your heart. There are ideas and methods to start.
(3) The ability to operate hands-on, that is, to participate in practical activities, learn to swim in swimming, and consolidate the theoretical knowledge learned in hands-on practice.
From the perspective of learning methods, reading a book can not solve the problem. If you read a book, you can't do it. You should read it systematically.
When reading a book, you must first read through 1 or 2 times. If you can understand it during the reading process, you can write it down. If you can't understand it, put it on the side and continue to look down. Don't intensively read the first time, you want to understand all the problems in the book. This is impossible and not scientific for beginners. After reading through several times, after having a certain overall understanding of the working principle of the circuit, then go to the whole book. In the course of study, a book should be used as the main textbook, supplemented by multiple books of the same type as reference books. When there are parts that cannot be understood in the main textbook, you can refer to the relevant parts of other books to understand the problem.
From the relationship between theory and practice, theory cannot be separated from practice, and practice should be guided by theory.
It is a good idea to look at the book and move it. In practice, if you encounter problems, ask for a book. This method of reading with problems is much better than reading alone. The perceptual knowledge learned in practice can deepen the understanding and understanding of theoretical knowledge.
From the hands-on operation, we should start from the simple, step by step, and gradually deepen. For example, familiarize yourself with the shape characteristics of some common components, learn to use a multimeter to check their quality, and don't start repairing electrical appliances from the beginning.
After the method suggests that you have some understanding of this subject, you should concentrate on your time and solve a small problem. For example, first analyze the working principle of the power circuit, and then try to install a small regulated power supply, and then learn to repair the power circuit failure. Specially learn the power circuit during a relatively concentrated period of time, so that you will have a deeper understanding of the power circuit until you can master it.
2. Learning should start with a wide range of electronic technologies from here, but learning should start with components.
The component is the smallest unit that constitutes the electronic circuit. It is the basis for analyzing the working principle of the circuit. It is also the object of final detection and replacement in the repair. From understanding and mastering the shape characteristics, structure, working principle, main characteristics and detection methods of the components, Then enter the learning of the working principle of the circuit. Of course, it is not required to understand all the components. The entry stage is mainly to understand the most basic components such as resistors and capacitors.
3. I can't remember and can't understand it. It doesn't matter if I can't remember and can't understand it. It's a normal thing and it is also common among beginners. The East that can't be remembered is something that is less frequently used and less frequently used. In the process of finding out the memory method that suits you, there are thousands of circuit diagrams, and it is simply impossible to rely on rote memorization.
Any problem that cannot be understood is because you have not mastered the basic knowledge in this aspect, or the basic knowledge is not comprehensive enough. Another possibility is that your own understanding method has a problem, and any problem is understood from the lower level, for example, no matter what. Circuits must analyze a current loop, which is a fairly wrong way to understand. On the one hand, it is because it does not learn circuit analysis well; on the other hand, it makes your study very tired, and the result is that the self-confidence of learning is lost, which is very harmful.
The method suggests that in the initial stage of learning, many things can't be remembered. One can put aside first, and as the study progresses, many problems will naturally disappear. Don't spend a lot of energy and time on one or two questions, which will affect your confidence in learning. Any problems encountered in practice can be clearly understood through theoretical study, and practical activities can strengthen memory.
4. Drawing a circuit diagram is a good way to learn the working principle of the circuit. In the process of learning the working principle of the circuit, after understanding the working principle of the circuit, you can draw the circuit diagram several times. It can test the learning effect and deepen the understanding of the working principle of the circuit. .
Any circuit that can be drawn very quickly is a part that is better mastered; the part that is always incapable of drawing or drawing is the weak link in learning.
When drawing a circuit diagram, it should be done according to the working principle of the circuit. Do not memorize or draw pictures.
5. The method of testing the learning effect of the self can analyze the circuit diagram that has been seen quickly and accurately, and can tell the working principle of the circuit in its own language. It can draw the learned circuit diagram without reading the book, indicating the circuit work. The learning of the principle has received good results.
6. Learning is very difficult. How to do everything is difficult at the beginning. It is very normal to learn the subject of electronic technology in the beginning stage. It is inevitable that you will not understand, remember, etc., but there is always a beginning and a start. process.
Recognizing the difficulty of learning the subject of electronic technology, we must establish the confidence that we can learn well, use scientific learning methods, and constantly summarize the memory skills that suit ourselves. It will be beneficial to persist for several months.
There are several main reasons for the many difficulties in the entry phase.
(1) The choice of teaching materials is incorrect. The starting point for the selected textbook is higher and should be learned from more basic textbooks.
(2) The method of learning is wrong. To increase the intensity of basic knowledge learning, we must be systematic, and more devoted to practical activities, expand the structure and face of knowledge, and build more perceptual knowledge.
(3) The study plan is too embarrassing. Temporarily narrow down and adjust the study plan, adjust the learning objectives, and set a learning plan that can be completed through hard work, and re-establish confidence in learning this technology.
(4) The package is not enough. The supporting work for learning is not comprehensive, such as just reading a book and not doing it.
7. Starting from the basics, step by step, the speed is not up to the circuit analysis or repair problems, especially the basic knowledge is not good. Some basic knowledge can be understood at a glance in the book. If you use it wrong, then the problem will come naturally. If you find that you don't understand a lot of questions when you read a book, it means that the preparation knowledge for reading this book is not enough. It should be seen from a more basic book.
You can't take a leap-forward learning. If you think you already know it, don't study hard. If you look at the content behind a few sections, there will be a lot of problems. The ancients cloud: the speed is not up.
