<p>There is described an RF receiver (300). The described RF receiver (300) comprises (a) an analog-to-digital converter (325) for converting an analog intermediate frequency band signal to a digital intermediate frequency band signal, (b) a plurality of decimation units (326) coupled in cascade for generating a decimated signal based on the digital intermediate frequency band signal, (c) a signal processing unit (328) for processing the decimated signal, and (d) a bypass path (329) for feeding a bypass signal to the signal processing unit (328), the bypass signal being either the digital intermediate frequency band signal or an output signal from one of the decimation units (326) which is not the last one of the cascade coupled decimation units (326), wherein the signal processing unit (328) is (e) adapted to detect critical reception conditions based on the bypass signal and (f) to adapt the processing of the decimated signal in accordance with detected critical reception conditions. There is further described a DAB radio apparatus, a method of receiving RF signals, a computer program and a computer program product.</p> |
