Abstract:
    A device includes a first mixer for production of a first analogue intermediate signal by down-mixing of a radio-frequency signal. The device also includes an A/D converter for production of a first digital intermediate signal, a second mixer for production of a second digital intermediate signal from the first digital intermediate signal, and a third mixer for production of a digital baseband signal from the second digital intermediate signal. The second mixer has a higher sampling frequency than the third mixer.
