摘要
LabVIEW对一般信号的分析处理非常强大、方便,能够胜任大多数测量任务,但对于需要进行大量数据运算处理的复杂应用,就显得力不从心。Matlab具有强大的计算功能、计算结果和编程可视化一体及较高的编程效率。因此根据两者的特长以及不足,本文给出了基于图形化编程软件LabVIEW和数学工具软件Matlab混合编程设计出小波消噪和小波突变信号检测的方法。仿真结果表明此方法是切实可行的,消噪效果明显,并成功的确定了原始信号的突变点。
For general signal analysis processing LabVIEW is very strong,convenient,and competent for measuring task,but not competent for the needs of large quantities of data of computing complexity application.Matlab has powerful calculation functions,the calculation result and the programming of a high and visualization programming efficiency.Therefore according to their specialty and insufficiency,wavelet de -noising and wavelet signal detection of mutations based on graphical programming software LabVIEW and mathematical tool software Matlab mixing programming design is given in this paper.Simulation results show that this method is feasible,de-noising effects obvious and successful determines the original signal mutations.
