웹2024년 3월 31일 · Ein Balun ( englisch balanced-unbalanced) ist in der Elektrotechnik und Hochfrequenztechnik ein Bauteil zur Wandlung zwischen einem symmetrischen Leitungssystem und einem unsymmetrischen Leitungssystem. Vor allem in der Hochfrequenztechnik wird für das Bauteil auch die Bezeichnung Symmetrierglied … Interfacing balanced and unbalanced lines requires a balun. For example, baluns can be used to send line level audio or E-carrier level 1 signals over coaxial cable (which is unbalanced) through 300 feet (91 m) of balanced category 5 cable by using a pair of baluns at each end of the CAT5 run. As the signal travels through the balanced line, noise is induced and added to the signal. As the CAT5 line is carefully impedance balanced, the noise induces equal (common-mode) voltag…
A balun /ˈbælʌn/ (from "balanced to unbalanced", originally, but now dated from "balancing unit") is an electrical device that allows balanced and unbalanced lines to be interfaced without disturbing the impedance arrangement of either line.
