翻訳と辞書　辞書検索 [ 開発暫定版 ] スポンサード リンク DSL filter ： ウィキペディア英語版 DSL filter A DSL filter or microfilter is an analog low-pass filter installed between analog devices (such as telephones or analog modems) and a plain old telephone service (POTS) line. The DSL filter prevents interference between such devices and a digital subscriber line (DSL) service connected to the same line. Without DSL filters, signals or echoes from analog devices at the top of their frequency range can reduce performance and create connection problems with DSL service, while those from the DSL service at the bottom of its range can cause line noise and other issues for analog devices. DSL filters are passive devices, requiring no power source to operate. A few high-quality filters may contain active transistors to refine the signal. == Components == The primary distinguishing factor between high-quality and low-quality filters is the use of transistors in high-quality (and more expensive) active filters, in addition to the usual components like capacitors, resistors, and ferrite cores, while the low-quality passive filters lack transistors. Transistors are active components that refine the signal. 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「DSL 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.
