If the power transmitted to the load before insertion is ''P''T and the power received by the load after insertion is ''P''R, then the insertion loss in dB is given by, :$10\; \backslash log\_$ ==Electronic filters== Insertion loss is a figure of merit for an electronic filter and this data is generally specified with a filter. Insertion loss is defined as a ratio of the signal level in a test configuration without the filter installed (|''V''1|) to the signal level with the filter installed (|''V''2|). This ratio is described in dB by the following equation: :$\backslash mbox\; =\; 10\; \backslash log\_\; =\; 20\; \backslash log\_$ Note that, for most filters, |''V''2| will be smaller than |''V''1|. In this case, the insertion loss is positive and measures how much smaller the signal is after adding the filter. 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「Insertion loss」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.
