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.)

128点FFT/IFFT变换
快速傅立叶变换(FFT)作为时域和频域转换的基本运算,是数字谱分析的必要前提。传统的FFT使用软件或DSP实现,高速处理时实时性较难满足。FPGA是直接由硬件实现的,其内部结构规则简单,通常可以容纳很多相同的运算单元,因此FPGA在作指定运算时,速度会远远高于通用的DSP芯片。FFT运算结构相对比较简单和固定,适于用FPGA进行硬件实现,并且能兼顾速度及灵活性。本文介绍了一种通用的可以在FPGA上实现128点FFT变换的方法。设计复数乘法器为核心设计了FFT算法中的基-2蝶形运算单元,溢出控制单元和地址与逻辑控制模块等其它模块,并以这些模块和FPGA内部的双口RAM为基础组成了基-2FFT算法模块。
