基于 Labview 的信号处理虚拟实验平台

摘要

In order to help students better understand the abstract concepts ,the theorems and the analysis methods in the signal processing courses ,this paper presents a Labview‐based virtual experimental system for signal processing ,mainly including the experiments such as the basic signal generation ,signal calculation ,sampling theorem ,image processing ,sound gathering and filter design .Taking the sampling theorem and DCT image compression as the examples ,the paper explains the method of realizing signal processing experiments with Labview .%为便于学生更好地理解信号处理类课程中抽象的概念、原理及分析方法，基于 Labview 构建了信号处理虚拟实验平台，包含基本信号的产生、信号的运算、采样定理、图像处理、声音采集以及滤波器设计等相关实验，并以采样定理和DCT图像压缩为例，阐明了利用Labview实现信号处理的方法。
