IIR
- 利用IIR滤波器对信号滤波,保留200Hz以下频率,使用CHEBY1滤波器-filtering to signal using IIR
iir_filter
- 用2个2级iir滤波实现的4阶iir滤波,采用16bit量化系数,其中14位有效位,经过与matlab的4阶iir滤波对比,输出结果完全一致。(The 4 order IIR filtering is implemented by two 2-level IIR filtering, and the 16bit quantization coefficient is adopted, in which 14 bit effective bits are compared with the 4 o
