发明名称 METHOD FOR MEASURING CROSSTALK IN ELECTRIC TELECOMMUNICATION SYSTEMS
摘要 Substantially orthogonal measuring signals are generated in a time or frequency domain in a measuring system (MS) on the basis of at least two vocal or test signals in order to measure the transmission characteristics in transmission lines mutually influenced by crosstalk in electrical telecommunication systems, specially in hands-free devices (FSE) to prevent said measurement from being distorted by crosstalk influences.
