The design process of a 128 times decimation filter based on Matlab is elaborated to introduce the two filter design methods, namely FDATool and Matlab language, and the simulated results are given.关键词: decimation CIC fliter compensation FDATool ...
Recently needed to see the effects of a CIC decimating filter but realized that with my new license of Matlab, I did not have access to the Filter Design Toolbox. This is a quick attempt at a simulation to re-create the effects of CIC-decimation but without the fixed-...
Part Number:ADS1299 1.用ADS采集数据,将时域的数据进行FFT变换,得到频谱里面看似有 Sinc Filter 抽取,不需要抽取是否可以?ADS可以不抽取看原始得数据吗? 2.这个和手册上的频谱不一样? 请问这个是什么问题呢? 您好, 您是将ADC采集的离散数据FFT吗?您是怎样进行的FFT,图中横坐标是频率吗? ADC...
demod M = 4 I / Q test mode, the coefficients of its decimation filter can be seen from the txt file, but the specific parameters of the cut-off frequency of the filter are unknown, please explain in detail.
The Anti-aliasing low-pass FIR decimation filter whose decimations are odd and high level can be instead of half-band filter. The MATLAB simulation result indicates that the cascaded digital decimation filter can not only effectively solve the problem of large and odd decimation, but also gain ...
The decimation filter design tool is developed using the graphical user interface development environment (GUIDE) in Matlabreg. The implementation complexity in terms of filter length that meets the specification for any of these standards is computed using this tool and is tabulated. 展开 ...
FIR filterdelta-sigma ADCThis paper study a kind of design method about the digital decimation filter design for delta-Sigma ADC with high performance and validated it by simulation using MATLAB tool. A 16-bit digital decimation filter design for stereo audio delta-sigma ADC has been developed....
Total three cascaded comb type filter are used for decimation and filtering purpose. Those filters are designed and simulated with MATLAB Filter Design Toolbox and finally mapped into XILINX SPARTAN-II XC2S50PQ208 series FPGA. The overall ADC gives 14 bit resolution.Subir Kr. Maity...
下图为某CICFilter的幅频特性(采样率=20M,R=5,D=5,级数=1) Figure8 特别注意,在使用Matlab的Fdatool设计CICDecimator时,有3个重要参数Decimation Facter(R),DifferentialDelay(M),NumberofSections(N) R与本文意义相同;D=R*M;N就是CIC Filter 的级联个数,N 不会改变0 值点和主瓣点 的位置,但N 增加会按...
In this paper, an area-efficient implementation of a multistage decimation filter for audio ΣΔ ADC is presented. The decimator with a decimation ratio of 256 has less than 0.005dB passband ripple and 100dB stop band attenuation. It has an audio passband of 0-20kHz and outputs 16-bit resol...
