基于虚拟仪器的FIR数字滤波器设计

Design of FIR Filter Based on Virtual Instrument

虚拟仪器(Virtual Instrument,简称VI)是基于计算机的仪器,是现代仪器技术与计算机技术相结合的产物,代表着仪器发展的最新方向与潮流。LabVIEW是美国NI公司推出的一种基于图形化编程语言(又称G语言)的虚拟仪器软件开发平台。本文介绍了一种基于LabVIEW平台的FIR数字滤波器的设计方法与实例。

Based on computer, Virtual Instrument （VI） is a combination of modern instrument technology and computer technology and represents the up-to-date orientation and trend of instrument development. Based on Graphics Language, LabVIEW is a software development platform for virtual instrument, which is developed by American NI Corporation. The paper introduces the design methods and examples of FIR digital filter, which are based upon LabVIEW platform.
