“信号与系统”课程教学仿真演示平台

Teaching Simulation Demonstration Platform for Signal and System

"信号与系统"是电气信息类本科专业的基础课之一,该课程理论性强,学习难度大。将信号运算、频谱分析、系统分析等知识点利用仿真演示平台配合传统教学,有助于学生掌握教学内容。开发的信号与系统教学仿真演示系统包括信号处理模块、信号和系统分析模块、信号处理应用模块、帮助模块等。该系统应用Matlab中的图形用户界面编程实现,具有良好的互动性。为配合教学,演示系统中包括了常用信号运算、信号分解、信号频谱分析、卷积运算、系统频率响应分析及各类应用等,同时为结合工程应用,系统中包含在通信、语音信号处理、图像处理领域的应用实例。该演示平台可作为传统教学的补充和辅助。

Signal and system is the fundamental course for disciplines of electrical engineering and information science. The courseis difficult to learn for theoretical intensity. Application of teaching demonstration system cooperated with traditional teaching ishelpful for students mastering teaching contents, which includes signal computation, signal spectrum analysis and system analysis.The platform is developed using graphical user interface of Matlab with good interaction. The system includes demonstrations abouttypical signal computation, signal decomposition, signal spectrum analysis, convolution, frequency response analysis and applica-tions. To cooperate with engineering application, examples concerning communication, audio signal processing and image process-ing are also provided. The proposed demonstration platform is the assistant for classical teaching.
