Introduces a SIR electric filter with improved stopband performance.
介绍了一种改进阻带性能的SIR滤波器。
The filter selectivity and stopband attenuation can be easily specified or controlled.
所设计滤波器的选择性和阻带衰减可预先给定并易于控制。
It can be found from the computer emulation that the IIR filter has the better passband and stopband characteristics than FIR filter with the same number of tap-weight.
从计算机仿真结果可以看出，当滤波器抽头数相同时，IIR滤波器具有更好的通带和阻带特性。
