摘要
LabVIEW是图形化虚拟仪器编程语言,它具有强大的数字信号处理功能。本文介绍了基于LabVIEW的数字滤波器的设计,它集FIR和IIR滤波器于一身,并且FIR滤波器的窗函数、IIR滤波器的模拟滤波器原型及滤波器的参数都很容易通过前面板来改变。仿真表明,所设计的数字滤波器滤波效果良好。
LabVIEW is a figural virtual instrument program language, which has powerful digital signal processing function. In this paper, a design of digital filter that includes IIR and FIR filter. The window functions of FIR , analog filter topologies of IIR and the coefficients of filter are changed easily by controllers on panel. Simulation shows that it is effective.
