摘　　要：在虚拟仪器(VI)LabVIEW6.i平台上,基于小波包变换算法设计了VI程序,实现了开关电源传导干扰信号实时检测系统。经过信号处理,该系统还具有信噪分离、测量传导干扰功率谱、伴有噪声的原始振动波形和噪声波等测量功能。实测结果表明,该方法是可行的和有效的。In virtual instrument（VI） LabVIEW 6.i software workbench, base on wavelet packet decomposition algorithm design is developed, combined with virtual instrument （VI） program, which realizes real--time detection system of the conduction interference signal in switches power supply. By signal processing. The system presented here have measurement functions as follow：signal-- noise to separate, measuring the power spectrum of conduction interference signal ,companion contain noise the conduction interference signals wave and noise wave etc. The result shows that this method is feasible and effective.
