摘　　要：针对MATLAB与LabVIEW软件的不同特性,提出利用编程实现和虚拟实验相结合的方式对信号进行处理,并以快速傅里叶变换FFT、信号的滤波,频谱分析为例,说明了这两种软件在信号处理中的特点及优劣性。通过实例表明采用MATLAB与LabVIEW两种软件可以实现动态演示和仿真分析的有机结合,从而可以提高信号处理的快捷性,直观性与可靠性。Aiming at the different characteristics between MATLAB and LabVIEW softwares,this paper puts forward a method combining programme and virtual experiment. Take fast Fourier transform（FFT）,filtering of signal and signal spectrum analysis as an example,it illustrates the features,advantages and disadvantages of the two softwares in the signal processing. Example indicates that using MATLAB and LabVIEW softwares can achieve combination of dynamic display and simulation analyses,and consequently increase shortcut,intuition and reliability of signal processing.
