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.
本文介紹了射電天文波段保護濾波器，它是一種結搆新穎的同軸帶阻濾波器。
In addition, the stop-band rejection can be further increased by using elliptic filter function which has limited frequency transmission zeros.
另外，在函數類型上使用橢圓函數型，使帶外出現有限頻率傳輸零點，進一步提高了帶外抑制能力。
The present paper reported the primary study on random bandpass and band-rejection filter module utilizing surface acoustic wave channelized technology.
報道了我們研制的一種採用聲表麪波信道化技術的隨機帶阻濾波組件。
