用Matlab实现了常见的几种滤波算法：中位值滤波，递推平均滤波，一阶滞后滤波等算法。可以直接运行-Using Matlab to achieve several common filtering algorithms: median filtering, average filtering recursive, first-order lag filtering algorithm. Can run

matlab仿真对采集数据进行滤波的两种方法：多次平均滤波和一阶滞后滤波的比较。-matlab simulation filtering the collected data in two ways: the average number of first order lag filter and the filter comparison.

限幅滤波和一阶滞后滤波，起到良好的声音改进效果-Limiting filter and a first-order lag filter, play a good sound effect improvements
