基于图形可视化Wintool和FDAtool的FIR滤波器设计

Design of FIR filter based on graph visualization Wintool and FDAtool

在大数据背景时代下,数据处理工具显得尤为重要,其中Matlab就是数据处理的一种有效的分析工具。Matlab具有强大的函数功能,可以通过编写M文件进行滤波器设计,同时可以通过图形可视化工具FDAtool和WINtool对系统阶次、窗函数类型、采样频率等参数的设置来设计系统。在可视化界面中可以很快捷地得到系统频谱图和时域特性图,便于用户进行系统稳定性分析,还可以将系统参数导出并保存为其他可处理的格式,从而方便用户在其他平台进一步进行系统设计和开发。

In the background of big data,the data processing tool becomes particularly important,in which Matlab is an effective analysis tool. Matlab has powerful function performance,and can used to design the filter by compiling M-file. The configuration of system order,window function type and sampling frequency is conducted by graph visualization FDAtool and WINtool in Matlab toolbox to design the system. The system spectrogram and time-domain characteristic diagram can be quickly obtained in visual interface,which is easy for users to analyze system stability. The system parameters can be derived and saved as other processable formats,which is convenient for customers to further design and develop the system in other platforms.
