bandpass filtering 中文意思是什麼
-
Two kinds of filters are presented : by transferring the conventional waveguide cavity filter to the siw, a narrow bandstop filter is designed and simulated, get characteristic of narrow - band bandstop filtering. for example, relative bandwidth 1. 2 %, most attenuation of 48db in band. electromagnetic bandgap ( ebg ) structures present “ forbidden band ” characteristics, siw features high - pass characteristics, so bandpass filters can be composed by combing ebg and siw
本論文提出了兩種基片集成波導濾波器結構:將傳統的腔體濾波器概念運用於基片集成波導結構，設計出了一種窄帶帶阻濾波器，對其進行模擬，得到了窄帶帶阻濾波特性，如相對帶寬為1 . 2 % ，最大衰減為48db 。 -
Frequency estimation technology and bandpass filtering, which are named as wideband digital downconversion technology, are the key technologies to realize data rate conversion system
測頻技術以及帶通濾波，即寬帶數字下變頻技術，是實現數據率轉換系統的關鍵技術。
