发明名称 METHOD FOR MEASURING CROSSTALK IN ELECTRIC TELECOMMUNICATION SYSTEMS
摘要 In order to be able to measure the transmission properties of transmission links mutually influencing one another with crosstalk in electrical message systems, particularly of handsfree equipment (FSE) such that the measurement is not falsified by occurring crosstalk influences, measuring signals that are essentially orthogonal are generated in the time or frequency domain in the measuring system (MS) from respectively at least two voice or test signals.
