摘　　要：为了研究滤波器设计及实现方式,用Visual Basic6.0软件研制出了FIR数字滤波器的设计软件。为了验证软件设计滤波器是否正确,给出了设计实例,并将设计的滤波器与matlab软件设计的滤波器进行了比较,结果表明,两种软件设计的结果相同。设计软件可将滤波器直接导出VHDL文件及系数文件,经QuartusII6.0软件综合后产生的网表文件可直接配置FPGA,实现了FIR数字滤波器的在线设计、在线修改。Abstract： In order to study the implementation and the des!gn of FIR digital ＂filter （ DF）, a software has been successfully developed to design FIR filter by Visual Basic6.0. To verify the correction of the software, some examples are given out, and the designed filters are eompared with ones designed by maflab. The result shows that there are no differences between them. The coefficients of FIR filter and the VHDL file can be directly output by the designed software, and the netlist file, generated by QuartusII6.0, can be used to configure the FPGA device. Therefore online design and modification of FIR DF can be realized.
