Broadband system e.g. asymmetric digital subscriber line system, for e.g. subscriber telephone exchange, has adaptation device adding generated compensation signal to broadband signal to compensate distortion of sinusoidal signaling signal

摘要

The system has an adaptation device (2) for generation of a compensation signal (KS) from a received broadband signal (eBS) which is superimposed with an amplified sinusoidal signaling signal of a audio system (3). The adaptation device adds the generated compensation signal to a broadband signal (sBS) to compensate a distortion of the sinusoidal signaling signal arising during amplification of the sinusoidal signal. - An INDEPENDENT CLAIM is also included for a subscriber telephone exchange with a broadband system.
