“信号与系统”课程体系剖析

A New Structure of Course System for Signals and Systems

"信号与系统"课程是一门重要的专业基础理论课。本文对该课程的体系进行了剖析,对串行体系结构和并行体系结构进行了分析,并总结提出了树状知识结构。该结构将"信号与系统"课程的知识按照由树根向各知识点扩展的结构组织起来,使课程体系结构清晰,便于联想学习和扩展学习等,为教师教学和学生提高学习效率提供借鉴。

Signals and Systems is an important basic course for students in the specialty of electronic and information engineering. This paper analyzes the system structure of the course to provide a reference for teachers and students who teach and study this course. It summarizes firstly the traditional serial and parallel system structures based on some classical textbooks, and then it proposes a new concept on the treebased system structure. The proposed system structure organizes curricular contents as a tree from the general concept of Signals and Systems which is referred to as the root to various knowledge points which is regarded as the leaves of the tree. The new system structure is more clear and convenient than the traditional structures.
