What is the employment scope of electronic information engineering?

Electronic information engineering covers a wide range. How to deal with all kinds of telephone signals in telephone exchange, how to transmit our voices and even images by mobile phones, how to transmit data by networks around us, and even how to keep secrets in the information transmission of the military in the information age. We can keep and develop more advanced technologies and new products by learning some basic knowledge. First of all, you should have solid mathematical knowledge and learn many basic courses such as circuit knowledge, electronic technology, signal and system, computer control principle, signal and system, communication principle and so on. I have to design it myself, connect some circuits and combine computer experiments. For example, I will connect the circuit of the sensor myself, build a small communication system with the computer, visit the electronic and information processing equipment of some big companies, understand the whole situation, understand how the mobile phone signal and cable TV are transmitted, and have the opportunity to participate in the design of large-scale projects under the guidance of teachers. With the increasing penetration of computers and the Internet into all levels of social life, the social demand is considerable. Now it's a hot major. What to do after graduation-engage in the design, application development and technical management of electronic equipment and information systems. With the deepening of social informatization, most industries need high-paid professionals. Can become: electronic engineer-design and develop some electronic and communication devices, the starting salary is generally 2000 -6000 yuan/month; Project supervisor-planning some large-scale systems requires high experience and knowledge, and the starting salary is generally above 4,000 yuan/month; You can also continue to study as a teacher and carry out scientific research projects. Specialty is a good specialty: it has a wide range of applications and intersects with computers, communications and electronics; But this line is biased, so the ability to do it is very important; In addition, it is best to be an undergraduate, and it is too difficult to find a job in a junior college now! Of course, in addition to prawns, this major has high requirements for mathematics and English, and if you are depressed, you have to get a high salary. To eat this bowl of rice, practical ability and mathematics are the basic skills. Of course, you are not required to be a mathematician, as long as you can understand formulas, such as calculus and probability statistics formulas, and at least know what you are talking about, while linear algebra requires more, because any book about an algorithm will eventually turn the algorithm into matrix calculation (so that you can program, and a considerable part of modern electronic engineering is programming). For hands-on ability, it is best to weld and assemble some small circuits in the lower grades. Tools? Just find the cheapest one! Electric soldering iron and multimeter are essential. Can I buy a second-hand oscilloscope circuit diagram if I have money? It is often published in radio magazines. Radio enthusiasts get started, and the actual operation is very good. The other is single chip microcomputer, CPLD/FPGA, DSP, among which single chip microcomputer is necessary, and 5 1 series single chip microcomputer can be used, because this is the most used one; Just find a 5 1 development board (cheaper) and program it yourself. ARM MCU, FPGA and DSP development board are all expensive, but this is the trend. If you can, have fun. Programming: c/c++ is a must. In fact, single-chip microcomputer /DSP application systems often use C language to develop data structures and operating systems, which is the core course of computer software specialty (Peking University teacher thinks that after learning these two courses, I think I have studied computers. Large single-chip computers (such as ARM series) often use embedded operating systems (such as uCLinux), so in addition to windows programming, I also have the opportunity to play the database principle of Linux programming and other computer majors (databases are too important now, so it is best to learn large-scale ones such as SQLServer and Oracle. You can also learn MySQL, Access), software engineering, computer architecture (if you have a solid foundation of microcomputer principle) and compilation principle (difficult enough) windows programming: beginners should use vb, and there are more Delphi/C++Builders really developed, so the cost of learning vc is too high. As for Java/C#, it is still far from the underlying development. There is also a write driver (WDM or Linux driver) at the bottom, but these are professional. In order to understand the operating system deeply, another big part of the electronic engineering course is the signal system, digital signal processing, communication principle, electromagnetic field and microwave technology foundation. These courses use a lot of mathematical knowledge. It's painful to learn, and I think it's difficult for undergraduates to understand these courses (because you don't have enough math foundation), but it's better to understand some in theory than in fog. Its employment direction includes applied electronics and signal and processing. Direction of applied electronics: (1) Modern electronic measurement technology is an essential technical quality for students of this major. As a basic course of electronic information engineering, Electronic Measurement Technology aims to enable students to master the basic measurement principles and methods of electronic quantities encountered in modern electronic measurement practice, and have the ability to analyze measurement errors and process measurement data. Have a certain understanding of the application of modern new technology in electronic measurement. Through the study of this course, it is very important to improve students' practical skills, cultivate rigorous scientific attitudes and methods, and solve practical problems in modern production and scientific research. It also lays a good skill foundation for subsequent production practice, graduation design and professional course practice. (2) EDA Technology is a professional technical course for electronics and electronic information majors. Through the teaching of this course, students are required to master the basic content and process of EDA, and be able to design practical digital circuits by using EDA software and hardware description language VHDL, and form practical circuits with large-scale programmable devices. At the same time, we should cooperate with the experiment, strengthen the cultivation of practical ability, and lay a solid foundation for the society. This course has 30 hours of theoretical teaching and 30 hours of practical training. This course should be conducted after studying electronic circuits, digital circuits, computer operations and other courses. (3) Radio and Television Reception Technology Radio and Television Technology is a practical course integrating theory with practice. As a part of theoretical study, through the study of relevant knowledge, students can comprehensively apply this knowledge in the process of analyzing and understanding the generation, transmission and reception of TV signals on the basis of the electronics theory and electromagnetism theory they have learned, and cultivate their ability to analyze and solve problems, and further cultivate their ability to maintain various electrical appliances. Combining practical teaching, we can cultivate students' practical ability, stimulate students' learning enthusiasm and lay a foundation for future study and work. (4) Intelligent Instruments This course is a specialized course for electronic information engineering. This paper introduces the basic composition, functional characteristics and development trend of intelligent instruments, and focuses on how to make electronic instruments intelligent by using microprocessor system, including related principles and specific software and hardware design methods.

Master the principles and design methods of three most representative intelligent instruments (voltage, frequency and oscilloscope), so as to establish the whole concept of intelligent instruments. Familiar with the basic design ideas and methods of virtual instrument based on graphic programming. 2. Direction of signal processing (1) Signal detection and processing "Signal detection and processing" is a basic technical course of this major.
