数字滤波器是由数字乘法器、加法器和延时单元组成的一种装置。其功能是对输入离散信号的数字代码进行运算处理，以达到改变信号频谱的目的。由于电子计算机技术和大规模集成电路的发展，数字滤波器已可用计算机软件实现，也可用大规模集成数字硬件实时实现。数字滤波器是一个离散时间系统.本文主要介绍了利用C语言实现巴特沃兹、切比雪夫，及任意幅度IIR滤波器的优化设计(直接型、级联型、并联型)，利用窗函数、切比雪夫逼近等方法设计FIR数字滤波器的方法．

digital wave filter is a kind of installation that forms by digital multiplier, adder and the unit of delay time. Its function is to carry out operational handling for inputing the digital code of dispersed signal in order to reach the purpose that changes signal frequency spectra. Because of the development of the computer technical circuit of large scale integration digital wave filter can already realize with computer software, can also realize with the digital hardware real time of large scale integration. Digital wave filter is a dispersed time system. This article mainly introduced realizes Butterworth using the C language, cuts compared to the snow husband, and the free scope IIR filter optimized design (direct, cascade, is parallel), using the window function, cuts compared to the snow husband approaches and soon the methods design FIR numeral filter method.
