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.

In electronics, signal processing, and video, ringing is oscillation of a signal, particularly in the step response (the response to a sudden change in input). Often ringing is undesirable, but not always, as in the case of resonant inductive co ...

In telecommunications, signal reflection occurs when a signal is transmitted along a transmission medium, such as a copper cable or an optical fiber. Some of the signal power may be reflected back to its origin rather than being carried all the ...
