A New Method To Design Eight-Band Directional Digital Filter And Its Realization

介绍了一种基于McClellan变换的八方向数字滤波器的设计方法,并用变换法设计实现了象限、扇形及其平行四边形的二维数字滤波器,通过相应变换进而得到八方向数字滤波器。对该算法进行MATLAB仿真的结果显示,该设计方法设计简单、结构简化,运算效率高,具有广阔的应用前景。

In this paper,eight-band directional digital filter based on McClellan Transform is discussed,and apply the method to design quadrant,fan and parallelogram digital filters,eventually eight-band directional digital filter is got.MATLAB Simulating results indicate that this method is simple to design,present simplified structure and efficient computing,and show the broad application prospect.
