说明：  65位FIR数字滤波器的设计~~其中有通过仿真得出得数据 ~可以通过数据输入完成滤波实验~对数字滤波器得整个算法进行了分析包括输入分组相加 然后相乘得过程
(65 FIR digital filter design ~ ~ with simulation data to come in through the importation of data from experiments completed filtering of the digital filter in the whole algorithm analysis including input a sum then multiply in the process)
