The connections between the cable shield and the metallic housings as well as the
connections between the shields of the different cable segments have to be low-
impedance (for high frequencies). As far as unshielded devices are connected to a
shield cable further methods may be applied to reduce the impact of noise (for
example galvanic isolation or filtering).
