Filters are data processing techniques that can smooth out high-frequency fluctuations in data or remove periodic trends of a specific frequency from data. In MATLAB®, thefilterfunction filters a vector of dataxaccording to the following difference equation, which describes a tapped delay-line fil...
Filter Data Filter Difference Equation(滤波器差分方程) 滤波器是一种数据处理技术,可以消除数据中的高频波动或从数据中去除特定频率的周期性趋势。 在MATLAB®中,滤波器功能根据以下差分方程过滤数据x的向量,该差分方程描述了抽头延迟线滤波器。 在该等式中,a和b是滤波器系数的矢量,Na是反馈滤波器阶数,Nb是前...

Filter Data in Sections Use initial and final conditions for filter delays to filter data in sections, especially if memory limitations are a consideration. Generate a large random data sequence and split it into two segments,x1andx2. x=randn(10000,1);x1=x(1:5000);x2=x(5001:end); ...
Selecting this option generates a function that takes data as input, and outputs data filtered with the designed filter. The data type of the filter output is set according to the data type settings in the Data Types pane. Clicking on the Generate MATLAB code button, brings up a Save File...
