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.
