摘要
在设计FIR数字滤波器时,采用基于查找表结构的分布式算法在性能方面要优于采用乘法器的算法。利用Matlab辅助滤波器设计,在ISE软件上进行了功能仿真、时序仿真和综合实现,最后在开发板上验证通过并对输出数据进行了频谱分析。该数字滤波器的设计目标为噪声环境下的基线测量。
Distributed Arithmetic is more efficient than multipliers for implementing finite impulse response （FIR）digital filters on an FPGA.The functional simulation,timing simulation and implementation of the FIR digital filter by using ISE,verify the results on the board and at last complete the spectrum analysis of the output signals by using Matlab.The digital filter is designed for the baseline measurement in a noisy environment.
