| 摘 要： | 对于给定的一组冲激响应数据,我们使用了几种IIR滤波器设计方法与之拟合,并对这几种设计方法的误差进行了比较.实验表明,在相同条件下,Matlab中的Stmcb函数误差最小;Lpc函数误差最大;其它几种方法相差不大.此外,给定的冲击响应非零区间越长,误差的累积越大.

| Abstract: | For a set of impulse response data, we use several IIR filter design methods to fit them, and give the comparison results through these methods. The experiment shows that under the same conditions, the Stmcb function of Matlab has the least error; Lpc function of Matlab has the most error; other methods give results without big difference. In addition, the longer the non-zero duration of an impulse response is, the bigger the accumulated error is. |
