Claim Text:
1. A method of matching signal transmission between two electronic devices connected to one another with a physical interface and each have a transmitter and a receiver, wherein signals are transmitted from the transmitter of one device along a transmission link to the receiver of the other device and wherein the transmission link has at least two signal lines (+, −) for differential transmission of the signals, comprising: A) detecting signal values on the receiver of the first device separately for each of the two signal lines (+, −), B) evaluating a mismatch between the signals from the two signal lines (+, −) on the receiver of the first device on the basis of the detected signal values, and C) changing one or more parameters of the transmitter in the second device separately and individually for the two individual signal lines (+, −) such that the signals on at least one of the two signal lines (+, −) are affirmatively provided with and subjected to imbalances in the transmitter of the second device prior to transmission, whereby after the transmission balanced signals from the two signal lines (+, −) are available on the receiver of the first device, wherein A), B) and C) are performed iteratively until a predetermined termination criterion is satisfied.
