Copy Code Copy Command Using the getFixedPointInfo function, you can determine the word lengths and fraction lengths of the fixed-point sections and the output of the dsp.CICDecimator and dsp.CICInterpolator System objects. The data types of the filter sections and the output depend on the Fix...
在设计CIC抽取滤波器时,需要导入FilterDesigner工具设计,但老出现“The fixed-point designer must be available to construct an mfilt.cicdecim filter.”这个报错问题,一直没有解决,怀疑是否为自己的Matlab版本问题,比较了伙伴的同版本的CIC设计,能够正常设计。

CIC(cascaded integrator-comb filter) 在软件无线电中,数字下变频器(DDC)接收经过,高速A/D采样得到中频数字信号,将其所需的频带下变到基带,它一般位于信号处理链的前端A/D,主要有数字振荡器(VCO)、数字乘法器、数字滤波器三部分组成,DDC后理论上我们就可以经过一个滤波器滤波,然后送到DSP或FPGA芯片中进行软件...

In the literature, we usually see that the group delay of a CIC filter is N*(R*M-1)/2. However, with the prepended zeros, dsp.CICInterpolator has a group delay of N*(R*M-1)/2 + N. The example code providedhereuses a lot of magic numbers. In particular, it plotsy(1,4:end...
