"Analog Electronic Circuits" is a required technical foundation course for registered audio-visual students majoring in applied electronic technology in the Central Radio and TV University. This course not only has its own theoretical system but is also a very practical course. The task of this course is to solve the problem of getting started with electronic technology, so that students can master the basic working principles, analysis methods and basic skills of analog electronic circuits, and lay a foundation for in-depth study of subsequent courses and practical work in related electronic technology.

2. Relationship with other courses

The prerequisite course is "Circuit and Magnetic Circuit". This course lays the necessary foundation for learning subsequent courses (such as "Modern Electronic Circuit and Technology", "Principles of Automatic Control", "Microcomputer Principles and Applications", etc.).

3. Course Features

The main features of this course are as follows:

Strong knowledge theory system - this means that learning this course requires a certain amount of basic theory and knowledge as a foundation, and it is also the basis for learning related subsequent professional courses;

The basic theory is relatively mature - although electronic technology is developing rapidly, new devices and circuits are changing with each passing day, its basic theory has formed a relatively stable system. Limited school teaching cannot be all-encompassing and comprehensive, so the focus of learning should be on learning and mastering basic concepts, basic analysis, and design methods;

Strong practical application and comprehensiveness - This course is a technical foundation course with strong practicality. Many electronic circuits discussed are practical circuits and can be made into actual devices. This feature of the course determines the importance of strengthening practical links and cultivating hands-on skills in this course.
