课程简介：
《信号与系统》是电类专业最重要的专业基础课程之一。整体是以两种系统和三个变换贯穿于理论知识的介绍。它的任务是从理论上建立完整的信号分析方法和系统模型。研究信号和线性时不变系统的基本理论和基本分析方法，要求从时域和变换域等多个角度，掌握基本的信号变换理论及线性时不变系统的分析方法，为学习后续课程，以及从事相关领域的工程技术和科学研究工作奠定坚实的理论基础。
通过本课程的学习，学生需要理解信号的函数表示与系统分析方法，掌握连续时间系统和离散时间系统的时域分析和频域分析，连续时间系统的W域、S域分析和离散时间系统的Z域分析，以及状态方程与状态变量分析法等相关内容。通过上机实验，使学生掌握利用计算机进行信号与系统分析的基本方法，加深对信号与线性时不变系统的基本理论的理解，训练学生的实验技能和科学实验方法，提高分析和解决实际问题的能力。是一门理论较深，概念较抽象，理论与实践紧密结合的重要而又不易掌握的专业基础课。
Course Introduction:
"Signal and system" is one of the most important professional basic courses in the electric speciality. The course includes two systems and three transformations. The task is to establish completed signal analysis methods and system models in the theory. The basic theory and basic analysis method are concerned with the signal and linear invariant system. The students need to grasp basic signal transformation theory and linear invariant system analysis method in order to lay a solid theoretical foundation for the study of follow-up courses.
Through the course of study, the students need to grasp the signal function and system analysis method, and master system analysis methods in the field of W domain, S domain and Z domain, and also the state equation and state variable analysis method and other related content. Through the related experiments, the students master the basic method of signal and system analysis, deepen the understanding about the basic theory of signal and linear invariant system. The object is to train students' experimental skills and scientific experiment method, improve the students’ ability of analyzing and solving practical problems. It is a deep theory, and the concept is more abstract, the theory is connected with the practical more deeper. The object is a important and also a difficult professional course.
