翻訳と辞書　辞書検索 [ 開発暫定版 ] スポンサード リンク Nonlinear distortion ： ウィキペディア英語版 Nonlinear distortion Nonlinear distortion is a term used (in fields such as electronics, audio and telecommunications) to describe the phenomenon of a non-linear relationship between the "input" and "output" signals of - for example - an electronic device. ==Model== For many devices, a linear model is accurate only for small signal levels. For example, at 2 volts input, a typical audio amplifier might put out 20 V, meaning the linear gain is 10 V/V. For 3 V input, it might then output 30 V. However, the model implies that at 50 V input it would produce 500 V, which is not possible with most amplifiers. Mathematically, the input-output relationship of many devices should be described by a polynomial or Taylor series, as shown below. $v\; =\; \backslash sum\_^\backslash infty\; a\_ku^k$ For larger values of ''u'', the higher order coefficients such as $a\_2$ and $a\_3$ come into play. 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「Nonlinear distortion」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.
