band-rejection filter

基本解释

This paper presents a filter protecting the radio astronomicalfrequency band, which is a novel coaxial band-rejection filter in structure.
本文介绍了射电天文波段保护滤波器，它是一种结构新颖的同轴带阻滤波器。
In addition, the stop-band rejection can be further increased by using elliptic filter function which has limited frequency transmission zeros.
另外，在函数类型上使用椭圆函数型，使带外出现有限频率传输零点，进一步提高了带外抑制能力。
The present paper reported the primary study on random bandpass and band-rejection filter module utilizing surface acoustic wave channelized technology.
报道了我们研制的一种采用声表面波信道化技术的随机带阻滤波组件。
