滤波器阻带 meaning in English

filter rejection band
filter stop band

The performance of filters is not very good . the attenuation of stop - band is almost - 44db . the performance cannot satisfy the requirement for some application situation
其阻带衰减大约在- 44db ，对于一些对滤波器阻带性能要求较高的应用场合，这个数值是达不到要求的。
The research productions of this thesis have much reference value on the filter miniaturization , improve the performance of filter stopband and improve the efficiency of the filter design
该课题的研究成果对于滤波器的微型化,滤波器阻带抑制的改善,以及提高设计效率等方面都有较大参考价值。
Thirdly , two kinds of the methods to improve the performance of filter stopband has been discussed . these methods are used to cleared up the influence of the parasitical passband . through the simulation and test result shows that these methods " s performance is expected
第三,论了2种对滤波器阻带抑制进行改善的方法,以消除寄生通带的影响,通过仿真和实际制作滤波器的测试结果。
