基于VHDL的一种数字低通滤波器设计

摘要

在了解FPGA设计原理的基础上，利用MAX＋plus软件和MATLAB，对横截型数字低通滤波器进行了设计，得到VHDL程序语言设计的相关参数；最后通过仿真对滤波器性能结果进行了分析和总结。%Based on the understanding of FPGA design principles,the cross section type digital low-pass filter was designed by using the software of MAX+plus and MATLAB.The relevant parameters of VHDL programming language were obtained.Finally results of the filter performance were analyzed and summa-rized by using the simulation.
