摘  要
 滤波器已经在现代化生活和生产中是必不可少的，无论日常生活中还是航空航天事业中，都随处可见！但我们对它的用途以及工作原理并不完全了解，本论文主要让大家能更好的了解滤波器的用途以及它的工作原理。
 首先本文初步介绍了什么是滤波器、模拟滤波器和数字滤波器的基本滤波原理以及模拟滤波器和数字滤波器的设计方法。接着用MATLAB对低通或者高通、数字或者及模的不同类型的波进行仿真滤波，让人家更加直观的了解滤波器。最后本文重点介绍了基于MAX262的程控滤波器的设计原理、设计思路、设计过程以及应用，让大家更加深入的了解程控滤波器的实质。

 Abstract
Filter in the production of modern life and is essential, both in daily life or in the aerospace industry, can be seen everywhere! But we incompletely understood to its use as well as the principle of work that, the present dissertation mainly enables everybody the better understanding filter use as well as its principle of work
First this article initially introduced any is the filter, the analog filter and the digital filter basic filter principle as well as the analog filter and the digital filter design method. Then uses MATLAB to the low pass or high pass, the numeral or and the mold different type wave carries on the simulation filter, lets others more direct-viewing understanding filter. Finally this article introduced with emphasis based on the MAX262 program control filter principle of design, the design mentality, the design process as well as the application, lets everybody more thorough understanding program control filter the essence.
