The Bergeron diagram method is a method to evaluate the effect of a reflection on an electrical signal. This graphic method—based on the real characteristic of the line—is valid for both linear and non-linear models and helps to calculate the delay of an electromagnetic signal on an electric transmission line. Using the Bergeron method, on the I-V characteristic chart, start from the regime point before the transition, then move along a straight line with a slope of ''Z''0 (''Z''0 is the line's characteristic impedance) to the new characteristic; then move along lines with −''Z''0 or +''Z''0 slope until the new regime situation is reached. The − value is considered always the same at every reflection because the Bergeron method is used only for first reflections. The method was originally developed by a French hydraulic engineer, L. J. B. Bergeron, for analysing water hammer effects in hydraulic systems. ==See also== * Ringing (signal) * Signal reflection 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「Bergeron diagram」の詳細全文を読む スポンサード リンク
