<signal-form-vehicle-electronic>
Within the transmission of data and electrical power via the vehicle network, these signals often are in a pulsed, periodic form. In order to reduce the radiation originated by these signals, general marginal conditions concerning their rise and drop times can be defined.
The signal characteristics will be defined generally for all interfaces. Furthermore, they can be defined contrary to this specification in the description of the interfaces for every connection. The signal characteristics can be defined by the parameters maximum voltage alteration and/or maximum current alteration.
