Evaluation of high definition digital video signal over coaxial transmission lines

摘要

In this paper, the propagation of two different digital video transmission standards have been evaluated over fifteen different coaxial cables. The frequency dependence of the attenuation for each cable and the maximum cable length for each standard have been obtained. The results show that the propagation properties improve with the inner conductor thickness and it is better to use coaxial cable with an inner conductor based on several filaments.
