针对数字滤波器对现场可编程门阵列(FPGA)的资源利用率过低的现状
对Meher等人提出的二维分布式有限长单位冲激响应(FIR)滤波器结构进行了改进
增加了延时模块
用二进制位权乘法(*2n)替代移位相加结构.提出了基于二维分布式算法的两种设计结构:"延时型"和"改进型"
并且应用FPGA实现了这两种结构.根据"改进型"和"延时型"两种结构分别设计了3

63阶Ⅱ型线性FIR滤波器.为验证"改进型"FIR滤波器的设计效果
应用Altera DE2开发板及其配套的AD/DA子板进行测试
结果显示:设计好的滤波器完全滤除了通带外信号
实现了带通滤波的目标.
The resource utilization of digital filters is low by using FPGA.Based on the two-dimensional(2-D) distributed structure of FIR filter presented by Meher
some improvements were made
included adding delay modules and binary weight multiplication(*2n)to replace shift and addition structure.Two structures
"time-delaying type" and "improvement type"
were designed and implemented on FPGA with orders of 3
