ABSTRACT:
The invention relates to a method and to a circuit configuration for adjusting the voltage level for the electrical data transmission between a transmitting component and a receiving component of one or different assemblies. According to the invention, the voltage level is increased step-wise or continuously until the required value for the correct representation of the signals to be transmitted is reached in the receiving component. Increase of the voltage level is stopped by the transmission of respective information. The inventive method and circuit are advantageous in that the minimum voltage level required for the transmission of data can be precisely adjusted. Power loss can be thereby reduced and adjacent channel interferences through high voltage levels can be reduced to a minimum.
