WHICH BOOK ARE THE 801 COMMUNICATION PRINCIPLES AND 804 SIGNALS AND SYSTEMS FOR THE COMMUNICATIONS POSTGRADUATE ENTRANCE EXAMINATION OF BEIJING UNIVERSITY OF POSTS AND TELECOMMUNICATIONS? _Baidu Knowledge...

There are two reference books on Principles of Communication: 1 Principles of Communication (Binding), Zhou Jiongman, Pang Qinhua, Xu Dawo, Wu Weiling, Beijing University of Posts and Telecommunications Press. 2 "Principles of Communication" Sixth Edition, Fan Changxin, National Defense Publishing House Signal and System Reference Book: "Signal and System Introduction" Zheng Junli, Higher Education Press.

Er.. The professional textbook is the most classic "Principles of Communication" of Beijing Post (edited by Zhou Jiongpan and others, Beijing University of Posts and Telecommunications Press) ~ and its after-class answer exercise collection ~ Personally, I think the most important thing to do at the beginning is to see through the textbook. If you can't see through and do more questions, you will have to be diluted. .

Do you mean the textbooks for the postgraduate entrance examination? The principle of communication is Zhou Jiongpan's "Principles of Communication" (the third edition and the joint edition are both available, Beijing University of Posts and Telecommunications Press), and the signal and system are used by Zheng Junli's "Introduction to Signals and Systems", which is the only edition of Higher Education Press.

"The Principle of Communication" edited by Zhou Jiongpan and others, edited by Beijing University of Posts and Telecommunications Press, "Signal and System" edited by Zheng Junli et al. Higher Education Press These two textbooks, and their corresponding exercises and answers are very important.Then the materials are the postgraduate entrance examination papers of previous years. The latter is quite useful and can be found on the Beijing Postman Forum.

Signal and System Introduction and What is the Difference between Signal and System

Signal and System Introduction The difference between Zheng Junli is that the content coverage is different, the language style and expression are different, and the target readership is different.

Signal theory includes: signal analysis, signal transmission, signal processing and signal synthesis; system theory includes: system analysis and system synthesis.

Signal and system problems are everywhere, and information science has penetrated into all modern natural and social science fields. Although the physical nature of signals and systems in various disciplines may be very different, they all have two very basic similarities.

Hello, I don't know which college you want to take the postgraduate entrance examination of "Electronics and Communication Engineering"? The professional course examination subjects of different colleges are slightly different.

What to learn about signals and systems

The signal and system course is an important disciplinary foundation for majors such as electronic information.The course is based on higher mathematics, linear algebra, basics of circuit analysis and other courses. It is also the basis for the follow-up study of professional courses such as communication system principles, digital signal processing and random signal processing, which has the function of inheriting the past and starting from the future.

"Signals and Systems" mainly talks about the time domain and frequency domain analysis of signals. The main contents include: the basic concepts of signals and systems; time-domain analysis, frequency-domain analysis and complex-frequency domain analysis of continuous signals and systems; time-domain analysis and z-domain analysis of discrete signals and systems; state variable analysis of systems, etc.

Signal and system is the core basic course of communication and electronic information major. The concept and analysis methods are widely used in communication, automatic control, signal and information processing, circuit and system and other fields.

This course mainly learnsIt is an idea that when solving problems in the future, we can regard the problem as a system. If there is input, then the output will be obtained, which is far-fetched. The main knowledge of signals and systems is Laplace transform, Fourier transform (discrete and continuous), z transform, and convolution. These parts can be said to be big heads.

The difference between Signal and System Introduction to Zheng Junli

There is no essential difference between the second edition and the third edition of Signal and System.

It's quite large. Zheng Junli's version focuses more on analyzing the system from the direction of the circuit. Personally, I feel that the Oppenheimer version is more authoritative.

The use of each hospital is not exactly the same, and everyone also has their own communication, mainly the one written by Zheng Junli.
