Improve of stopbandattenuation and passband fluctuation.
带内波动、带外抑制特性的改善。
2
The filter selectivity and stopbandattenuation 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。
3
The bandpass filter that has spurious suppression characteristics can solve this problem and it has excellent bandpass symmetry and stopbandattenuation characteristics at high frequency.
