Bergeron diagram
Encyclopedia
Bergeron diagram method is a method to value the reflection's effects on an electric signal. This graphic method—based on the real line's characteristic—is valid both for linear and non linear models and helps to calculate the delay of an electromagnetic signal on an electric line.

characteristic chart start from the regime point before transition, then move with a straight line with Z0 slope (Z0 is the line's characteristic impedance
) to the new characteristic; then move with lines with −Z0 or +Z0 slope until reaching the new regime situation.
The − value is considered always the same at every reflection because the Bergeron method is used only for first reflections.

Electric current
Electric current is a flow of electric charge through a medium.This charge is typically carried by moving electrons in a conductor such as wire...

Voltage
Voltage, otherwise known as electrical potential difference or electric tension is the difference in electric potential between two points — or the difference in electric potential energy per unit charge between two points...

Characteristic impedance
The characteristic impedance or surge impedance of a uniform transmission line, usually written Z_0, is the ratio of the amplitudes of a single pair of voltage and current waves propagating along the line in the absence of reflections. The SI unit of characteristic impedance is the ohm...
