OVERSAMPLING IN ANALOGUE-DIGITAL AND DIGITAL-ANALOGUE CONVERTERS
摘要
The invention relates to a method and a device for the digital transmission of analogue signals, whereby an oversampling in analogue-digital and digital-analogue converters is carried out. A digital-analogue conversion is thus carried out which is particularly suitable for VDSL systems. A transmitted digital transmission signal (110) is supplied to a mixing unit (201). The digital transmission signal (110) is superimposed on a received noise signal (211), in the mixing unit (201) and applied to a received noise source connection (209). An interpolation filter unit (203), combined with a serial noise generation device (205), provides an increase in the frequency band width such that a suitable oversampling is achieved.
