With the rapid development of science and technology, emerging disciplines are constantly improving. It no longer just refers to a certain subject taught by teachers in the classroom. The total amount of knowledge continues to grow, forcing undergraduate education to continue to move toward basic courses. It refers more to
A series of courses or a curriculum-oriented, application-oriented development, basic course teaching in the undergraduate education group'1J.
This requires teachers to take a higher and higher position in research in basic course teaching.
With the gradual deepening of education reform, starting from the talent cultivation model, focusing on the entire process of talent training and integrating it, the connotation and functions of basic courses are constantly expanding and comprehensively optimizing the basic curriculum system structure.

Wanfang Data Journal of Changzhou Institute of Technology in 2009 "Circuit Analysis" and "Signals and Systems" are both systematic disciplines in the electrical teaching content, strict barriers between courses, and important basic courses for each major. "Digital Signal Processing" is
The situation of self-governance of electronic information requires strengthening the intersection between different disciplines and courses. Important basic courses for majors such as information engineering and communication engineering are 口qo.
Integration, in accordance with the training objectives, build a new curriculum system that is integrated, closely coordinated, and has "circuit machine connection" with the rapid development of electronics, computers, communications and other technologies. The content of the analysis course is constantly updated, but the theories involved are several (
2) While correctly handling the relatively stable relationship between the constant updating of teaching content and the relatively stable relationship between the teaching content and the mature classic courses that focus on basic circuit theory and basic analysis methods, it is necessary for students to select core content, merge and suppress theories, which is indispensable for students to study subsequent courses.
The basic knowledge is reduced or eliminated, old and repetitive content is expanded, advanced ideas are included, and knowledge is reorganized. A considerable part of the content is related to the knowledge unit of the "Signals and Systems" course.
Increasing engineering background knowledge and application prospect analysis are inseparable.
"Signals and Systems" and "Digital Signal Processing" courses strengthen the awareness of comprehensive engineering applications.
Without increasing class hours, the teaching content of the course also has an inseparable internal connection. Under this principle, curriculum integration should be strengthened and students' basic knowledge structure should be reconstructed.
The first line is to realize the processing of different signals through the analysis of various signals. (3) Strictly follow the higher industrial student numbers formulated by the Ministry of Education to achieve the desired signals.
In the past two decades, the basic requirements for school curriculum teaching have been implemented to implement teaching and select teaching materials to ensure that with the development of science and technology, computers have become the basis for obtaining and analyzing certificates without reducing teaching requirements; the main content must be explained clearly and thoroughly, and signals must be corrected and processed.
As an important tool, signal analysis and processing are almost non-main content. There should be no missing items, but they should also be concise and to the point, and penetrate into various engineering fields, so that the connotations of "signal" and "system" can be explained in a simple way, so that they can be used as a practical guide.
Spend.
The extension has been greatly expanded, and digital signal processing has also become an extremely important high-tech field. With people's increasing requirements for signal processing, there are some insurmountable problems in analog signal processing. 2.1 "Circuit Analysis"
The shortcomings of the course are that many signal processing turns to digital methods (1) Two types of constraint relationships in lumped circuits.
Based on the circuit topology.
Today, the theory and technology of digital signal processing itself include Kirchhoff's law of structure and the volt-ampere characteristics of resistive elements.
It has also become an important branch in the discipline of signal and information processing. (2) Using the analysis method of independent current and voltage variables.
Moreover, with the rapid development of electronic technology and computer technology, mesh analysis method, loop analysis method, and node analysis method have emerged.
to widespread application.
Therefore, the three courses "Circuit Analysis", "Signals and Systems (3) Fundamental Theorems of Circuits. Superposition Principle, Substitution Theorem, System" and "Digital Signal Processing" constitute the information and communication Thevenin's theorem, Norton's theorem, maximum power transmission
theorem.
(4) Capacitive components and inductance components. Capacitive components and inductance theory” basic course system that is important in the information engineering major.
The volt-ampere relationship of components, energy storage, and the nature of capacitor voltage and inductor current.
and "Digital Signal Processing" courses are taught in their own way, with (5) first-order circuits.
Time constant, general solution, special solution; zero input response, zero state response, complete response, three-element method due to repeated teaching content, unreasonable connection, insufficient synthesis, etc.
First-order problems, these problems are solved with the modification of teaching plan and the transient response of AC sinusoidal circuit during class.
The reduction appears more prominent.
For example, in traditional "circuit analysis" (6) second-order circuit.
Zero Input Response of an RLC Series Circuit The complete response of a connected, dc RLC series circuit has been covered in many Signals and Systems courses.
Continue the relevant content of signal and system analysis, and the course "Digital Signal (7) Sinusoidal Steady State Analysis. Kirchhoff's Theorem in Phasor Form" also contains a large number of laws and three basic laws in the "Signal and System" course
The phasor form of the volt-ampere relationship of circuit components, the interference signal and the repetition of the system analysis content.
Each course covers its own reactance and admittance, as well as the analysis of sinusoidal steady-state circuits using the phasor method.
3. The optimal content system is not necessarily the optimal AC circuit for the entire teaching plan.
1. Therefore, the teaching content of the original course system must be carried out (8) Circuit analysis containing coupled inductors.
