band-rejection filter

基本解釋

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(hù)濾波器，它是一種結(jié)構(gòu)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(shù)類型上使用橢圓函數(shù)型，使帶外出現(xiàn)有限頻率傳輸零點(diǎn)，進(jìn)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(bào)道了我們研制的一種采用聲表面波信道化技術(shù)的隨機(jī)帶阻濾波組件。
