Abstract
The invention creates a method and a device for digitally transmitting analog signals, in which oversampling is performed in analog/digital and digital/analog converters. In this arrangement, a digital/analog conversion is performed which, in particular, is suitable for VDSL systems. A transmitted digital transmission signal () is supplied to a mixing unit () and in the mixing unit (), a receive noise signal () applied to a receive noise source terminal () is superimposed on the digital transmission signal (). An interpolation filter unit (), in combination with a subsequent noise shaping device (), provides an increase in the frequency bandwidth, resulting in suitable oversampling.
