Advanced Mathematics-(Mathematical Analysis+Spatial Analytic Geometry+Ordinary Differential Equation) mainly focuses on calculus. For those who study circuits, calculus (one variable, multiple variables), curve and surface integrals, series, ordinary differential equations, etc. are often encountered in subsequent theoretical classes.

Probability statistics-Probability theory is used in all courses related to communication and signal processing.

Methods of mathematical physics-some schools learn them after graduate students, others are divided into complex variable function (+integral transformation) and mathematical physics equation (that is, partial differential equation). Learn the mathematical basis of electromagnetic field and microwave.

It is also possible to establish a stochastic process (based on probability) or even a functional analysis.

② Theory:

Circuit principle-basic course.

Signal and System-Time and frequency domain analysis of continuous and discrete signals is very important, but it is also very difficult.

Digital signal processing-discrete signal and system analysis, digital signal conversion, digital filter, etc.

Basically, both require a lot of algorithms and programming.

Communication principle-mathematical theory of communication.

Information theory-information theory has a wide range of applications, but electronic engineering majors often refer to this course as coding theory.

Software basics-(data structure of computer major+algorithm+operating system+database principle+compilation method+software engineering) may also be several courses, which talk about the principle of software and how to write software.

Detailed course introduction:

①c language

C language is a widely used computer language at home and abroad, and it is a programming tool that computer application personnel should master.

C language has rich functions, strong expressive ability, flexible and convenient use, wide application, high efficiency of object program and good portability. It has the characteristics of both high-level languages and low-level languages. So C language is especially suitable for writing system software.

After the birth of C language, many softwares originally written in assembly language can now be written in C language.

Novices should not abuse some error-prone details of C prematurely, such as improper use of++and-side effects. When learning programming, you must learn to use it flexibly. Don't learn to use it, but draw inferences from others, so that you can master a new language quickly when you need it later.

② Advanced Mathematics

Advanced mathematics is an important basic subject in universities of science and engineering. As a science, advanced mathematics has its inherent characteristics, namely, high abstraction, strict logic and wide application. Abstract is the most basic and remarkable feature of mathematics-high abstraction and unity, which can profoundly reveal its essential laws and make it more widely used. Strict logic means that in the induction and arrangement of mathematical theory, whether it is concept and expression, or judgment and reasoning, we must use the rules of logic and follow the laws of thinking. Therefore, mathematics is also a way of thinking, and the process of learning mathematics is the process of thinking training. The progress of human society is inseparable from the wide application of mathematics. Especially in modern times, the appearance and popularization of electronic computers have broadened the application field of mathematics. Modern mathematics is becoming a powerful driving force for the development of science and technology, and it has also penetrated into the field of social sciences extensively and deeply. Therefore, it is very important for us to learn advanced mathematics well. However, many students are confused about how to learn this course well. If you want to learn advanced mathematics well, you must at least do the following four things:

First, understand the concept. There are many concepts in mathematics. Concepts reflect the essence of things. Only by figuring out how it is defined and what its essence is can we really understand a concept.

Secondly, master the theorem. Theorem is a correct proposition, which is divided into two parts: condition and conclusion. In addition to mastering its conditions and conclusions, we should also understand its scope of application and be targeted.

Third, do some exercises on the basis of understanding the examples. Especially remind learners that the examples in the textbook are very typical, which is helpful to understand concepts and master theorems. Pay attention to the characteristics and solutions of different examples, and do appropriate exercises on the basis of understanding examples. When writing a topic, you should be good at summing up-not only the methods, but also the mistakes. You will gain something after doing this, so you can draw inferences from others.

Fourth, clear the context. We should have an overall grasp of the knowledge we have learned and summarize the knowledge system in time, which will not only deepen our understanding of knowledge, but also help us to further study.

③ Signals and systems

Signal and system is the core basic course of communication and electronic information specialty, and its concepts and analysis methods are widely used in communication, automatic control, signal and information processing, circuits and systems.

According to the characteristics of online courses, this course uses multimedia technologies such as pictures, words, sounds, images and animations to make the content vivid and easy to understand. Supported by network technology, this course focuses on students' autonomous learning, combined with teachers' questions and answers, students' discussions and other forms, which makes the course reflect the characteristics of interactivity, openness, autonomy and cooperation.

Conceptually, this course can be divided into two parts: signal decomposition and system analysis, but they are closely related. According to the decomposition of continuous signals into different basic signals, the corresponding analysis methods of linear systems are derived as follows: time domain analysis, frequency domain analysis and complex frequency domain analysis; Discrete signal decomposition and system analysis are similar processes.

This course adopts the layout knowledge of continuous and then discrete, so we can concentrate on learning the content of continuous signal and system analysis first, and then understand the concepts of discrete signal and system analysis through analogy. Combined with two modules, the state analysis method is given, thus the complete concept of signal and system is established.

In addition to the main contents required by the syllabus, this course also gives random signals through linear system analysis, discrete Fourier transform, FFT and other contents to expand the knowledge.

④ Circuit analysis

Circuit analysis is a very important technical basic course for electrical specialty in engineering colleges. This course not only lays the foundation for the following professional courses, but also plays a very important role in developing students' scientific thinking and cultivating their ability to analyze and solve problems. The main contents of this course include: basic concepts and laws of circuits, equivalent transformation of resistance circuits, basic analysis methods and theorems of linear circuits, circuit analysis with ideal operational amplifiers, steady-state analysis of sinusoidal AC circuits, circuits with mutual inductance, three-phase circuits, periodic non-sinusoidal current circuits, two-port networks, time domain analysis of first-order circuits, time domain analysis of second-order circuits, Laplace transform and its application, state variable method, nonlinear resistance circuits, etc.

⑤ Microcomputer principle

The emphasis of microcomputer principle is to introduce instruction system and interface, which is very important to understand the hardware principle of microcomputer. If microcomputer is needed for control and communication, microcomputer principle is a compulsory course. Therefore, the principle of microcomputer is listed as one of the main courses by most majors.

C language is considered as a programming language between high-level language and assembly language, also known as intermediate language. Many operating systems are implemented in C, such as Unix, Linux, minix and so on. Many low-level communication programs, drivers, encryption programs, etc. They are all written in C, the important reason is that C language is very close to assembly language, in other words, C language is close to computer hardware, but at the same time C language programming is much more convenient than assembly, so many people.

Generally speaking, learning the principle of microcomputer does not need the foundation of C language, but really understanding and mastering C language is a necessary foundation. For example, pointer operation in C requires understanding the structure of microcomputer memory.

Unfortunately, at present, most colleges and universities in China take the C test first and then the microcomputer principle. The author thinks that this is really misleading and is not conducive to the cultivation of high-level talents.

In addition, some people think that microcomputer principle, as an important course connecting hardware and software, has not been paid enough attention in colleges and universities, which is not commensurate with the status of this course.

⑥ communication principle

As a practical system, communication is produced to meet the needs of society and individuals, with the purpose of transmitting information (data, voice and images). The development of communication technology, especially in recent 30 years, has formed the main theoretical system of communication principle, namely coding theory, modulation theory and detection theory.

In the course of communication principle, there are many places to use the conclusions or theorems of information theory. Information theory has become a guide for designing communication systems and conducting communication technology research, especially it can tell engineers the performance limit of communication systems.

There is noise in the channel. Noise and interference are inevitable in communication. With the study of noise and interference, stochastic process theory came into being. The analysis of signals is actually the analysis of stochastic processes.

In the field of communication engineering, coding is a technology that can be realized by hardware or software. There can be many codes in mathematics, which can be mapped to different spaces, but they can only be applied to codes that can be generated and recognized in communication systems. The combination of coding theory and communication forms two directions: source coding and channel coding.

Modulation theory can be divided into linear modulation and nonlinear modulation. The difference between them is that linear modulation does not change the spectral structure of the modulated signal, while nonlinear modulation changes the spectral structure of the modulated signal, which often occupies a wider frequency band, so nonlinear modulation usually has better anti-noise performance than linear modulation.

The receiver separates the modulated signal from the carrier signal, and the process of recovering the modulated signal is called demodulation or detection.

As a course of communication principle, it also includes system contents, mainly including synchronization and channel multiplexing. In digital communication system, only when the received signal is synchronized with the transmitted signal or the same time relationship is established between the signals, the receiving end can demodulate and identify the signal. In order to improve communication efficiency, channel multiplexing is a protocol or specification that arranges many signals to pass through the same channel at the same time, so that the voice, image and other messages of multiple users can be transmitted through the same cable or other channels at the same time.

On the basis of communication principle, it is a professional course to further explain the design of communication system or deepen a certain theory or technology. To design and manufacture communication systems, we need to know the principle, but it is not enough to know the principle. You must also be familiar with hardware (circuit, microwave) and software (system software and embedded software), which is another branch of the professional course plan.

The teaching of communication principle course is mainly divided into two parts: analog communication and digital communication. The emphasis is on modulation, coding and synchronization of digital communication.

With the completion of the teaching content, students are required to complete the necessary exercises. During this period, some verification experiments are provided, and at the same time, SystemView experiment teaching is used to let students know more about the actual work of communication system.

Because it is difficult for students to understand the communication principle, teachers have strengthened the multimedia CAI teaching of this course, and vivid and intuitive illustrations have assisted the teaching. Teaching is carried out by using the electronic lesson plan demonstration successfully developed by the course group and the graphic aided teaching software with difficulty simulation as the main part. Greatly improved the teaching effect. At the same time, the online experimental teaching software is being developed successfully, and the use of teaching instruments and the simulation experiments of important experimental instruments are put online to further meet the requirements of teaching informationization and networking. In a word, this course greatly improves students' understanding of the teaching content of this course through theoretical teaching, experimental teaching, curriculum design, CAI courseware, comprehensive design and network teaching.

⑦ Digital circuit

The basic course of digital circuit starts with the most basic gate circuit, and reaches the basic composition and working principle of various common flip-flops, encoders, decoders, memories and sequential circuits. The course patiently explains the basic knowledge and analysis methods of various digital logic circuits, such as what is truth table, what is competitive adventure phenomenon, why computers use binary in various systems, why we often use 16 system, etc., until we can see the world. After reading these, we can understand the origin of digital circuit and find that it is not mysterious, even simpler than analog circuit! With these basic understandings, we can learn and analyze other advanced knowledge of complex digital circuits by ourselves.

⑧ Analog electronic circuit

First, the nature, purpose and task of the course.

Analog electronic circuit is a compulsory technical basic course for electronic information technology major in the Open Institute of Technology of China Central Radio and TV University. This course not only has its own theoretical system, but also is a practical course. The task of this course is to solve the problem of introduction to electronic technology, so that students can master the basic working principle, analysis method and basic skills of analog electronic circuits, and lay a foundation for further study and practical work related to electronic technology in subsequent courses.

Second, the relationship with other courses.

The prerequisite course is the basis of circuit analysis, which lays the necessary foundation for the following courses (such as Modern Electronic Circuit and Technology, Automatic Control Principle, Microcomputer Principle and Application).

Third, the characteristics of the course

1. Knowledge theory is systematic. Learning this course needs to be based on certain basic theories and knowledge, and it is also the basis for learning related follow-up professional courses.

2. The basic theory is relatively mature. Although electronic technology is developing rapidly and new devices and circuits are changing with each passing day, its basic theory has formed a relatively stable system. Limited school teaching can't cover everything. We should focus on learning and master basic concepts, basic analysis and design methods.

3. The practical application is comprehensive. This course is a very practical technical basic course. Many electronic circuits discussed are practical circuits and can be made into practical devices.
