摘要
讨论了数字滤波技术,介绍了在LabVIEW和VisualC++环境下,应用动态链接库(DLL)技术实现数字滤波器开发的方法和步骤,编制了数字滤波器子程度MyFilter.vi。将开发的MyFilter.vi与LabVIEW自带的中值滤波器进行比较,发现利用该程序滤波后的数据更加接近了原有的数据采集器采集到的数据.弥补了LabVIEW中数字滤波器子程序的不足。
This paper describes the development of the digital filter by using Dynamic Link Library (DLL) technology under the condition of LabVIEW and Visual C++. The subprogram for the filter,My Filter. Vi, is coded and compared with the median filter of Lab VIEW. It is found that the data filtered by My Filter. Vi is closer to the original data than by the filter of LabVIEW,and the deficiency of the Lab-VIEW filter is made up.
