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 (110) is supplied to a mixing unit (201) and in the mixing unit (201), a receive noise signal (211) applied to a receive noise source terminal (209) is superimposed on the digital transmission signal (110). An interpolation filter unit (203), in combination with a subsequent noise shaping device (205), provides an increase in the frequency bandwidth, resulting in suitable oversampling.

Abstract: A comb filter arrangement has an integrator that outputs an input value to a signal path. The signal path includes a delay stage for adjusting the input value using a delay factor, a decimator that converts the input value into a decimated output value using a non-integral factor, a differentiator that generates an intermediate output value from the input value, and an interpolation arrangement that receives the intermediate output value and generates a decimated sequence of the output value.
