代码说明:

  文章运用分级抽取和多相滤波的方法改进传统CIC滤波器的结构,降低了系统工作频率,运用幅度改进函数(ACF)和外加级联余弦预滤波器的技术改进了滤波器频率响应,提出了一种高效的算法结构,改善了通带损耗,增大了阻带衰减,对CIC滤波器的实际应用和深入研究有着现实意义。 (Article the use of hierarchical multi-phase extraction and filtering methods to improve the structure of the traditional CIC filter, reducing the system operating frequency, the use of margin to improve the function (ACF) and the cosine cascade plus pre-filter technology to improve the filter frequency response, the an efficient algorithm to improve the pass-band loss, increases the stopband attenuation of the CIC filter in practical applications and in-depth study has practical significance.)

    耳蜗实质上相当于一个滤波器组,耳蜗的滤波作用是在对数频率尺度上进行的,在1000HZ下,人耳的感知能力与频率成线性关系;而在1000HZ以上,人耳的感知能力与频率不构成线性关系,而更偏向于对数关系,这就使得人耳对低频信号比高频信号更敏感。Mel频率的提出是为了方便人耳对不同频率语音的感知特性的研究。频率与Mel频率的转换公式为(Cochlear substantially equivalent to a filter set, cochlear filter is used on logarithm frequency scale, under the 1000 hz, the perception of the human ear and a linear relationship with frequency In more than 1000 hz, the perception of the human ear does not constitute a linear relationship with frequency, and prefer to logarithmic relationship, which makes the human ear is sensitive to low frequency signal is better than high frequency signal. Mel frequency is put forward in order to facilitate the ear of the study of speech perception characteristics of different frequency. For frequency and Mel frequency conversion formula )
