Übertragungslänge

Übertragungslänge refers to the physical length of a transmission line used to carry electrical signals. This length is a critical parameter in electrical engineering and telecommunications, as it significantly influences the behavior of signals propagating along the line. For direct current (DC) or low-frequency alternating current (AC) signals, the Übertragungslänge has a negligible impact on the signal's characteristics. However, as signal frequencies increase, the physical length of the transmission line becomes comparable to the wavelength of the signal.

At these higher frequencies, phenomena like signal reflection, impedance mismatch, and attenuation become significant. The Übertragungslänge affects the phase shift of the signal as it travels, leading to constructive or destructive interference at the receiving end. It also influences the magnitude of signal loss due to resistance and other dissipative effects. Understanding and accounting for the Übertragungslänge is essential for designing efficient and reliable communication systems, power transmission grids, and high-frequency electronic circuits. In many applications, transmission lines are designed to be electrically short, long, or resonant based on their physical Übertragungslänge relative to the signal wavelength.
