STM32F407FFT
说明: 使用STM32官方提供的DSP库进行FFT,虽然在使用上有些不灵活(因为它是基4的FFT,所以FFT的点数必须是4^n),但其执行效率确实非常高效,看图1所示的FFT运算效率测试数据便可见一斑。该数据来自STM32 DSP库使用文档(. Using the official DSP library provided by STM32 for FFT is not flexible in use (because it is the FFT of base 4, so the number of FFT points must be 4 ^ n), but its execution efficiency is really very efficient, as can be seen from the test data of FFT operation efficiency shown in Figure 1. This data comes from STM32 DSP library usage document)

CICFilter
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.)
