离散时间系统分析教学大纲 （双语课）安徽大学计算机科学与技术学院二O一七年二月Discrete-Time System AnalysisCourse SyllabusNature, Task and Aims of the CourseThe course of Discrete-Time System Analysis is one of main elective courses for students majoring in computer science and technology or in computer network engineering. The aim and objectives of this course is to introduce the fundamental theory of discrete-time systems, with emphasis on linear time-invariant systems, to students in such a way as to enable them to specialize in diverse areas like communication systems, control systems, and signal processing. The main topics of this course include the fundamental concepts of discrete-time signals and systems, convolution representation, the z-transform, and discrete-time system analysis in the time domain and the z-transform domain. After completing this course the student should have acquired a good grounding in the fundamentals of discrete-time systems.Requirements for Learning: By the end of the course students should have knowledge and understanding of: Basic discrete-time signals Classification of discrete-time systems Basic system properties Discretization in time of differential equations Complete solution of linear difference equations with constant coefficients Convolution representation of linear time-invariant discrete-time systems Convolution of discrete-time signals Definition of the Z-transform; Region of convergence for Z-transform; Properties of the z-transform Inverse Z-transform Stability of discrete-time systems Frequency response of discrete-time systems Analysis and characterization of linear time-invariant discrete-time systems using z-transformPrerequisitesContinuous-time signals and systems, Differential equations, linear algebra.Scheduled Lecture Hours and Credit Points 34 lecture hours, 2 credit points.Course Text E.
