摘要
介绍了信号处理与分析课程实时动态实验演示系统的设计理念与实现方法。利用具有图形化用户接口、并为使用者提供了数据采集、信号分析处理和信号的输出与显示功能的交互式C语言LabWindows/CVI开发平台,将课程中枯燥的原理、理论及计算方法等内容分别设计成不同的演示模块,实现了“软件即仪器”的思想,在课堂上通过多媒体展示给学生,将理论知识形象化,激发了学生的学习兴趣,有效地提高了课堂教学质量。
Dynamic demostration system for signal processing course is introduced. Based on the C language development platform LabWindows/CVI with graph user interfaces （GUI） which provides user the functions of flexible data acquisition, signal analysis and processing, signal output and display on the windows platform, several virtual instrument GUI models are designed. It makes use of the strong signal processing library functions to realize the idea ‘ The software is the instrument,＇ so that it can achieve the purposes of visualizing the principles and improving teaching effects effectively.
