Signal and System Postgraduate Entrance Examination

. Signal and System is a major professional basic theoretical course in electronic information disciplines. It is a compulsory course for communication engineering, electronic information engineering, electronic science and technology, automation and other majors. It has the characteristics of combining circuits, engineering mathematics, and putting equal emphasis on physical concepts and theoretical calculations.

The postgraduate entrance examination subjects of electronic information engineering include: mathematics (higher mathematics, linear algebra, probability statistics), English and politics. Most school professional courses include: digital circuits, analog circuits, signals and systems.

Signal and information processing are generally tested: signal and system and digital signal processing.Circuit and system directions are generally tested: signal and system, analog electronic technology, circuit, etc. The direction of electromagnetic field and electromagnetic wave is generally tested: electromagnetic field and electromagnetic wave, antenna, microwave, etc.

The postgraduate entrance examination subjects of communication and information system are: ideological and political theory, English mathematics communication and signal system. "Communication and Information System" belongs to the first-level discipline of "Information and Communication Engineering". It is a national key discipline and a special professor of the Yangtze River Scholars Program. In 1986, this discipline was approved as a doctoral point.

Qidao Education summarizes the scope of 847 signals and systems according to the previous Xiamen University postgraduate entrance examination. The concepts of signals and systems mainly include the definition and classification of signals; the operation of signals; the definition and division of systems; the definition and characteristics of linear time-invariant systems, etc.

You learn the communication principle in blocks. Random signal analysis and channel are one, and analog modulation system and analog signal digital transmission are the second block. The digital baseband transmission system and sine carrier digital modulation, and the best reception of digital signals are the third block, and the knowledge of coding is the fourth block. Finally, synchronization technology is the fifth block.

What are the subjects for the postgraduate entrance examination of computer information security major??

Which subjects are required for the computer postgraduate entrance examination: the computer postgraduate entrance examination requires four comprehensive subjects of political theory, foreign language, mathematics I and computer science. The total scores of the test papers are 100, 100, 150 and 150 respectively.

Computer postgraduate entrance examinationSubjects: political theory, foreign language, mathematics I and computer science major basic comprehensive, the full score of the paper is 100 points, 100 points, 150 points and 150 points respectively.

Computer composition principle, data structure and algorithm. According to the information released by China Education Network, the postgraduate entrance examination for information security requires subjects such as computer composition principle, data structure and algorithm.

Information security postgraduate entrance examination subjects: Take China Civil Aviation University as an example, the postgraduate entrance examination subjects include 101 ideological and political theory, 204 English (II), 302 mathematics (II), and 408 computer science professional foundation. English II Examination Content: Application of English Knowledge Mainly examines the candidates' ability to comprehensively apply English knowledge.

Information security postgraduate entrance examination subjects: (101) ideological and political theory, (201) English (301) mathematics (859) cryptography.(The scope of the professional course examination is slightly different depending on the college.)

The computer postgraduate entrance examination requires political, English and professional courses. The first professional course is the professional basic course or mathematics, and the second professional course is the professional comprehensive course. Usually, the re-examination is organized by the enrolling institutions and the assessment content is announced. The subjects generally include computer professional courses, spoken foreign languages, basic quality and comprehensive ability, etc.

2_8 Signal and System Exercises

1, y1(n)=T[x1(n)], y2(n)=T[x2(n)], if T[x1(n)+x2(n)]=y1(n)+y2(n ) and T[a1x1(n)]=a1y1(n), then it is a linear system, and the system that performs sampling, quantization and multiplication of the signal is not a linear system.

2. The waveform shown in the figure on the right of the single item selection of the first chapter introduction can be expressed as (D) by the unit step function.

3. Understand the spectrum of the sampling signal and its solution, and understand the sampling theorem. 1 Understand the basic theorems and applications of modulation and demodulation.

4. What are the power signals and what is their average power? Ω0tω0tj (ω0t+θ) (2)ε(t)ε(t1)(5)3e(8)cos solution: 4+sin5(2)E=limT→∞T∫Tf(t)dt=2∫11dt=120 Therefore, the signal is a pulsed energy signal.

5. For causality, that is, compare the size of t and sint, because sint is sometimes greater than t, so it is non-causal. Very clearIt is shown that it is linear. If it is proved, y(t)=ax1(sint)+bx2(sint)=ay1(t)+by2(t) when input x(t)=ax1(t)+bx2(t).

Experience in the postgraduate entrance examination of electronic science and technology of Sichuan University?

Undergraduate School: Changsha University of Technology Major: Electronic Science and Technology Final Postgraduate Entrance Examination: School of Physical and Electrical Engineering of Hunan University With the gradual announcement of the proposed admission notice, the 22 postgraduate entrance examination is almost over. As a lucky person who has been admitted, I would like to share my postgraduate entrance examination experience here. Check.

Successfully landed in the year, the preliminary examination score was 331, the master's degree, the professional course score was 127, and the English score was 64., Mathematics 1 73, Politics 67, according to the postgraduate entrance examination results of previous years, it is not high, passed the preliminary examination score line of electronic science and technology of Xi'an University of Posts and Telecommunications, and finally successfully landed.

Recommended institutions: China University of Political Science and Law, Renmin University of China, East China University of Political Science and Law 0 Major in Electronic Science and Technology This is a very high-level major ~ The foundation of information science is microelectronic technology and optoelectronic technology, which belong to a first-level discipline "electronic science and technology".

The learning vein of Sichuan University can be traced back to the Sichuan Chinese and Western School founded in 1896. The university was formed by two mergers of three national key universities, the former Sichuan University, Chengdu University of Science and Technology and West China Medical University.
