摘要
数字滤波器作为信号处理领域不可或缺的重要组成部分,受到了广泛关注,其设计方法一直是业界重要的研究课题。为了高效的实现数字滤波器,文中以LabVIEW为平台,基于图形化的界面和数字化的指标,抛开传统滤波器设计中的繁琐计算和变换,设计带窗的数字滤波器和低通滤波器,并给出了实例。实验仿真结果表明所设计的滤波器达到了应用需求。
Digital filter works as an important part of signal processing which has received extensive attention, and its design methods have been the hot research subject in this area. In order to implement digital filter efficiently, LabVIEW platform is used in this paper. LabVIEW is based on the graphic interface and digital parameters, and avoids complex calculations and transformations comparing with traditional method of filter design. In this paper, two designs which are digital filter with window and low-pass filter have been given. The simulation results show the two designs of filter can satisfy the requirement of application.
