Method and cable for connecting electronic equipment to another electronic equipment

摘要

A connection method and a connecting cable for improving transmission of low-frequency signals and reducing the radiation level of high-frequency signals. To connect electronic devices via a connecting cable, the region between the ends of the signal line of a connecting cable is shielded by a first external conductor. Then one end of the first external conductor is connected to a reference potential of a first electronic device. The first external conductor is shielded by a second external conductor, and the second external conductor is connected to a reference potential of a second electronic device. The reference potentials of the first and reference potentials of the second electronic devices are coupled through a stray capacity between the first external conductor and the second external conductor. The length of opposition between the first and second external conductors is adjusted according to a frequency for suppressing radiation.
