Definition: | ratio of the phasor representing the reflected voltage to the phasor representing the incident voltage at a port of an electric network or close to a discontinuity in a transmission line
NOTE 1 – At a port of an electric network, the complex voltage reflection factor is by convention the negative of the complex current reflection factor. NOTE 2 – When impedances can be defined, the complex voltage reflection factor equals: $\underset{\_}{r}=\frac{\underset{\_}{Z}\prime -\underset{\_}{Z}}{\underset{\_}{Z}\prime +\underset{\_}{Z}}$
where ′ is the impedance after the discontinuity or the load impedance seen from the junction between the source and the load.
ZNOTE 3 – The terms "complex voltage reflection factor" and "complex tension reflection factor" may be shortened by omitting "complex" and/or "voltage" or "tension" in an appropriate context. | ||
