摘要
详细探讨了两种不同的数字低通滤波器设计方法,即全极点法、双线性变换法。每种方法各有其优点,通过计算,我们得出结论全极点法优于双线性变换法,更加灵活。
Two different methods of design low pass digital filter have been discussed in detail in this paper,namely the bilinear transformation and the all pole transformation.Each method has its advantages,but it will be seen that all polar design gives superior selectivity,and all polar filter is more flexible than the former approach.
