使用命令y = filter(hd,X)即可,hd = dfilt.dffir(b);b为滤波器系数,X为你的原始数据,y即为滤波后数据。你在fdatool下点击targets,然后点generate C header,就可以把系数产生在一个文档里面,复制到workspace里面就可以调用了。
Learn how to implement tunable and non-tunable digital filters for FIR and IIR filter implementations in Simulink® using DSP System Toolbox™. Use non-tunable filters when the filter response is known and fixed during simulation. On the other hand, tunable filters allow modification...
Simulink环境可近似为理想环境,因此我们将System Generator滤波结果与Simulink的滤波结果作对比。添加Digital Filter Design到model中,该block的配置界面与FDATool工具完全相同,对输入信号进行滤波。此时model如下: 将Digital Filter Design与Digital FIR Filter的滤波器参数设置为完全相同(20Mhz采样、1.5MHz通带截止...
System Generator是Xilinx公司进行数字信号处理开发的一种设计工具,它通过将Xilinx开发的一些模块嵌入到Simulink的库中,可以在Simulink中进行定点仿真,可以设置定点信号的类型,这样就可以比较定点仿真与浮点仿真的区别。并且可以生成HDL文件,或者网表,可以在ISE中进行调用。或者直接生成比特流下载文件。能够加快DSP系统的开发进...
sysgen_filter_bd是调用System Generator导出的IP核的子模块。16Bits输入数据经过滤波后得到36Bits的输出结果。运行RTL ANALYSIS,打开RTL视图,找到最底层: 可以看到其本质上仍然是调用了FIR Compiler IP核来实现数字滤波,只不过我们是在Simulink中完成的设计。在其它工程中可以像示例工程一样调用这个System...
Discrete FIR Filter(Simulink)andBiquad Filter— Use to efficiently implement floating-point or fixed-point filters that you have already designed. These blocks provide the same exact filter implementation as the Digital Filter Design block. Filter Realization Wizard— Use to implement floating-point or...

digital filter design Abstract: With the information age and the advent of the digital world, digital signal processing has become one of today's most important disciplines and door technology. Digital signalprocessing in communications, voice, images, automatic control, radar, military, aerospace, me...
The low pass, high pass and notch filters were designed using MR filter technique. These filters are used to remove noise in ECG signal. Comparison of performance for various low pass, high pass and notch filter are studied for final design model of Simulink which will give optimum solution ...
