  • Radio reception apparatus and method for the control of a radio reception apparatus
    Patent number: 6501944
    Abstract: The invention relates to a method for the control of the bandpass width in the filtering of an intermediate frequency signal of an audio receiver of a radio reception apparatus. A signal parameter of a user signal of the audio receiver which is received at a reception frequency is determined and taken into account and a signal parameter of at least one neighboring signal which is received at a neighboring frequency which is adjacent to the reception frequency is determined. The bandpass width of the intermediate frequency filtering is selected in dependence at least on the signal parameter which is determined from the user signal, on the signal parameter which is determined from the neighboring signal and on the frequency distance between the reception frequency and the user frequency. Furthermore, the invention relates to a corresponding radio reception apparatus.
