摘要
虚拟仪器技术是电子测量技术与计算机相融合的一项测控领域的新技术,图形化语言LabVIEW是虚拟仪器技术的开发平台,其库函数中有用于各种数学运算及信号处理的函数模块.本文就信号处理中常用的多项式最小二乘法滤波、数字信号的数值微分方法,及其LabVIEW实现做了介绍.在数据处理上,利用LabVIEW工具库3次样条插值函数,实现数值微分运算的算法设计,并讨论了其在微分电位溶出分析仪上的应用.
Virtual instrument technology is an advanced technique of electronic measurement and control,which merges computer and electronic measurement technology.LabVIEW is a graphical programming language that is the Integrated Development Environment of Virtual Instrument,and includes many signal progressing and mathematics analysis function modules.A method of the polynomial least square filter and the digital differential in signal processing is introduced in this paper,and is discussed how to realize by using LabVIEW in details.In data processing,the Cubic Spline Interpolant function module included in LabVIEW tools is used to implement the algorithm of numerical differentiation operation.Its application to the differential potentiometric stripping analysis instrument is also discussed.
