LabVIEW语言是一种功能强大的虚拟仪器开发平台,利用它实现小波变换的Mallat算法,并运用滤波算法对小波系数进行处理,实现信号的滤波,再重构得到所需要的真实信号,从而实现LabVIEW的二次软件开发;并成功应用于焊接电流信号的滤波分析处理,得到了真实的焊接电流信号。
LabVIEW is a kind of developing fiat of virtual instrument with powerful function.Wavelet transform's algorithm of Mallat and wavelet filtering algorithm to wavelet coefficient are realized by the Second development of LabVIEW.Then actual signals are restructed by processed wavelet coefficient.It is successfully applied in de-noising of welding current,and actual welding current signals are attained.
