针对课程教学中的信号分析与处理内容，基于LabVIEW软件平台，设计开发了测试技术虚拟实验教学系统。将抽象的概念、定理、数学变换、信号的时域分析和滤波去噪等理论，形象直观地进行演示和验证，既节省了实验经费，又提高了教学效果；系统的开放性和模块化设计特点,又为学生的自主学习和创新实验设计提供了平台。

Virtual experiment teaching system based on LabVIEW software platform was developed for teaching of signal analysis and process in packaging test technology. The system can make some theories, such as abstract concepts, theorems, mathematics transform, signal analysis of time domain and filtering denoising theory, more directly to perform and proving. By this way, funds were saved and teaching effect improved. The open and modular design characteristics of the system provide a platform for students' independent learning and innovation experimental design.
