Abstract

The apparatus includes a mobile receiver for digital audio broadcasting. The transmission process is substantially entirely digital and a whole frequency range is used for the terrestrial transmission. The apparatus includes a receiver for a digital radio signal, particularly wherein the filter coefficient is changeable by a control circuit which generates a first value for the filter coefficient to get the real signal component and thereafter generates a second value for the imaginary signal component, whereby with the switching over of the first and second values for the filter coefficient a simultaneous downsampling of the digital signal is performed.
