Second, in order to understand the circuit diagram conveniently and quickly, it is necessary to master the knowledge of unit electronic circuits composed of some common components, such as rectifier circuit, filter circuit, amplifier circuit, oscillator circuit, power supply circuit, etc. Because these circuit units are common functional blocks in the circuit diagram of electronic products, mastering the knowledge of these unit circuits can not only deepen the understanding of electronic components, but also get exercise in understanding and reading the circuit diagram through such "primary exercises". With this knowledge, I have laid a good foundation for further understanding and reading more complex circuits, and it is easier to deepen my study.
Three, should know more, familiar with and understand the basic concepts in the circuit diagram. For example, the potential of key points, how the potential of each point changes, how to connect with each other, how to form loops and paths, which constitute DC loops, which form signal channels, which belong to control loops and so on.
To understand and read the circuit diagram of an electronic product, you need to have a general understanding of the electronic product, such as the main functions of the product and which circuit units it may consist of. This can avoid detours when understanding and reading its circuit diagram.
Five, often look for familiar components and unit circuits in the circuit diagram to see what role they play in the circuit, and then contact the surrounding circuits to analyze how these external circuits work together with these components and unit circuits, and gradually expand until you can understand the whole picture.
Six, constantly try to divide the circuit diagram into several rules and regulations, and then break them one by one to understand the function and working principle of these rules and regulations one by one, and then connect the rules and regulations to understand and read the whole circuit diagram.
7. Look, read, analyze and understand various circuit diagrams. You can change from a simple circuit to a complex one. When you encounter a problem that is difficult to understand at the moment, you can not only think independently, but also consult experts and experts. You can also read more textbooks and articles in this field (for example, the May 6th electronic website is a good place for everyone to learn) and learn from it. It is not difficult to read the circuit diagram quickly as long as you persist in pursuit, work hard, but it is just around the corner to become an expert in electronic technology.
