Design and Simulation of Digital Filter based on LabVIEW

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.
