低通滤波器的C语言实现，开发环境visual c 6.0或者keil环境-Low-pass filter C language, development environment, visual c 6.0 or keil environment

基于51单片机的C语言代码，指数加权平均算法滤波函数，也是一个一阶低通滤波器。文件中有比较详细的注释。-Based on the the 51 microcontroller C language code, exponentially weighted average algorithm filtering function is also a first-order low-pass filter. Detailed notes in the file.

程控滤波器的程序，可以实现高通滤波和低通滤波，中心频率可调。-Programmable filter program, you can achieve high-pass filter and low-pass filter, the center frequency is adjustable.
