利用AVR单片机设计IIR 低通滤波器，其中截止频率、抽样频率都有说明，运行环境是先用IICAVR建立工程，再将该代码加入进去即可-Use AVR microcontroller IIR low-pass filter, which cut-off frequency, sampling frequency with specifications, running environment is to use IICAVR build project, then the code can join

利用matlab实现IIR滤波器的设计，其中包括Butterworth滤波器的设计、冲激响应法和双线性变换法-IIR filter design using matlab, including the design of the Butterworth filter impulse response method and the bilinear transform

IIR数字滤波器的设计 上学的时候一直不知道如何用C语言来编写IIR滤波器，终于找到了，上传给大家 希望能帮到大家。-IIR digital filter design when the school did not know how to use C language to write IIR filters, and finally found it, upload to hope to help you.
