TI中文支持网我想实现一个1阶高通滤波器，在matlab中通过FDATool工具，导出了相关的数据，如下：
/*
* Filter Coefficients (C Source) generated by the Filter Design and Analysis Tool
*
* Generated by MATLAB(R) 7.2 and the Signal Processing Toolbox 6.5.
*
* Generated on: 16-Aug-2013 09:03:09
*
*/
/*
* Discrete-Time IIR Filter (real)
* ——————————-
* Filter Structure : Direct-Form I
* Numerator Length : 2
* Denominator Length : 2
* Stable : Yes
* Linear Phase : No

* Implementation Cost
* Number of Multipliers : 3
* Number of Adders : 2
* Number of States : 2

#include "tmwtypes.h"
/*
* Expected path to tmwtypes.h
* C:\Program Files\MATLAB\R2006a\extern\include\tmwtypes.h
*/
/*
* Warning – Filter coefficients were truncated to fit specified data type.
* The resulting response may not match generated theoretical response.
* Use the Filter Design & Analysis Tool to design accurate
* single-precision filter coefficients.
*/
const int NL = 2;
const real32_T NUM[2] = {
1.000200033, -1.000200033
};
const int DL = 2;
const real32_T DEN[2] = {
1, -0.9991999865
};
现在的问题是，通过这个东西，怎么样在2812中编出IIR滤波器来？或者说，知道了滤波器Z域传递函数，怎么编出IIR滤波器来？ 本人对这些东西不太懂，求指点，如果有相关例程更好了，谢谢大家了

Yangyang,
C2000在滤波器上有相应的库和例程，下载ControlSUITE软件，参照

应该是在controlSUITE的安装目录下啊，不是在tidcs中。

Yangyang 你好 ，
具体的路径在ControlSuite->libs->dsp->FixedPointlib中。例程中有些关键的代码是不可见的，只要会调用函数就行。
