Experience sharing of postgraduate entrance examination of photoelectronics and photonics technology of Tianjin University?

In the middle of the last century, the theory and technology of holographic and optical information processing based on Fourier optics were born.

In fact, it is not difficult to ask questions in Tianda University, and the signal itself has a routine to follow. After learning your own framework, it is easy to get a high exam.At that time, learning signals and systems was mainly textbooks + some after-class questions + past papers of my choice. The specific time plan will not be elaborated here. In fact, everyone should have their own arrangements.

Optoelectronic information science and engineering is an emerging interdisciplinary discipline. It integrates the knowledge of electronics, optics and information science and technology and other related disciplines, focusing on the study of basic issues such as light-electron interaction, information processing, transmission and storage.

That's a good question. The process of microelectronics has now encountered a technical bottleneck. It's good for you to develop into optoelectronics. But in the next ten years, it will still be dominated by microelectronics. Optoelectronics is a new field. Who doesn't want to make breakthroughs in new fields? Sensors have been very popular recently, which is a harbinger of the development of optoelectronics.

Whose video is better to watch in the postgraduate entrance examination signal and system

1. Zheng Junli's version of "Signal and System", the institution's course, for the explanation of the past exam questions of Beijing Post, is still good, you can refer to it, but the content is relatively Less, very fine. Li Xuewu and Wu Da of Western Power's genuine version of "Analysis of Signals and Linear Systems" is for Western Power. If you just want to listen to the textbook, it is not recommended.

2. Signal and linear system Zheng Junli version is good. Zheng Junli's version of "Signals and Systems", the lecture of the institution, for the explanation of the past exam questions of Beijing Post, is still good, which can be referred to, but the content is less and very detailed.

3. First of all, if you don't know the direction you want to take, you can choose professional courses without hurry.First, review public courses. Public courses include English, mathematics and politics. If readers want to take the humanities exam, then mathematics is generally not taken, but science, engineering and management are generally mathematics.

4. You can choose to watch Guo Baolong's video of Western Power, which can have a deeper understanding of many knowledge points. Guo Baolong's video did not finish the knowledge points of the postgraduate entrance examination, so it was combined with Chen Houjin's course later.

5. If you study the genuine signal and system of Western Power Wu University, it is recommended that you read the signal and system boutique course of Western Power. If you study Zheng Junli Signal and System, this is not a very good boutique course, but many schools use this textbook, you can refer to the teaching videos of these schools.

6. Hello, poster, if you want to take the examFor academic graduate students, Beijing Post Communication needs to take two professional courses: "Communication Principle" and "Signal and System", which are comprehensive papers, the former accounting for 90 points and the latter accounting for 60 points, a total of 150 points. If it is professional, Beijing Post Communication only takes the exam of "communication principle", which is 150 points.

It's just that the enrollment is divided into directions, and what you come in to do is still related to your own teacher.

3. I have participated in the 22-year postgraduate entrance examination. I applied for a master's degree in software engineering from Ocean University of China, and I am currently going to be admitted.My preliminary examination score is 76 in politics, 73 in English II, 100 in mathematics II and 122 in computer major. The total score in the preliminary examination is 370, ranking fourth in the major, and the third in the re-examination in the major. I have the following experience in reviewing for the postgraduate entrance examination.

4. According to the official website of Communication Engineering of Ocean University of China, the re-examination adopts on-site re-examination or network remote re-examination. For details of the re-examination method and re-examination content of each unit, please refer to the implementation rules for re-examination admission announced by the faculty and college (center).

5. At that time, it will become the main campus of Ocean University of China.) No. 238 Songling Road, Qingdao City (When I have a chance to go to Qingdao to find you to climb Laoshan. Although I have been there once, I didn't climb to the top, only half of it! Ha ha.

6. China's ocean bigInterpretation of basic information of school enrollment Ocean University of China, abbreviated as OC, formerly known as Qingdao Ocean University, is located in Qingdao City, Shandong Province.

Familiar with the major of signal and information processing (postgraduate entrance examination) Come in~~~Urgent~!!!

Signal and information processing is a first-level discipline under information and communication engineering. At present, the core discipline of information technology provides basic theories, basic methods, practical algorithms and implementation schemes for communication, computer applications, and various information processing technologies.

The biggest difference is the learning direction and employment direction of the three majors. SignalAfter information processing, you can go to a communication company to do network optimization. The treatment is good, and it is relatively stable in the communication industry.

Communication is very popular in China now. For example, some large enterprises of Huawei and ZTE are starting from communication. Signal processing is mainly divided into two directions: voice and image. As for the signal, it is not recommended to be a theory for domestic employment. Embedded should be a very good choice, especially DSP. There are not many people in China, and the treatment is very good.

The major of signal and information processing in the Graduate School of Civil Aviation University of China is better. The Graduate Department of Civil Aviation University of China is located at Tianjin Binhai International Airport. It is a relatively young graduate department, but the postgraduate education of Civil Aviation University of China has a long history.
