翻訳と辞書　辞書検索 [ 開発暫定版 ] スポンサード リンク RF and microwave filter ： ウィキペディア英語版 RF and microwave filter Radio frequency (RF) and microwave filters represent a class of electronic filter, designed to operate on signals in the megahertz to gigahertz frequency ranges (medium frequency to extremely high frequency). This frequency range is the range used by most broadcast radio, television, wireless communication (cellphones, Wi-Fi, etc.), and thus most RF and microwave devices will include some kind of filtering on the signals transmitted or received. Such filters are commonly used as building blocks for duplexers and diplexers to combine or separate multiple frequency bands.〔http://www.rfcafe.com/vendors/components/filters.htm〕 ==Filter functions== Four general filter functions are desirable: * Band-pass filter: select only a desired band of frequencies * Band-stop filter: eliminate an undesired band of frequencies * Low-pass filter: allow only frequencies below a cutoff frequency to pass * High-pass filter: allow only frequencies above a cutoff frequency to pass 抄文引用元・出典: フリー百科事典『 ウィキペディア（Wikipedia）』 ■ウィキペディアで「RF and microwave filter」の詳細全文を読む スポンサード リンク 翻訳と辞書 : 翻訳のためのインターネットリソース Copyright(C) kotoba.ne.jp 1997-2016.
