所实现的二维数字滤波器不仅保持贝塞尔滤波器通带内相位线性、阻带内相位近似线性的优点,而且能利用一维至二维的双线性变换压缩过渡带,使过渡带变得陡峭、阻带衰减增加。
The realized 2-D IIR filters not only keep the advantages of the linear phase charateristics in the pass band and approximately linear phase charateristics in the stop band , but also compress the transition band to be steep and increase the attenuation of stop - band .
