ABSTRACT:
To support a plurality of different mobile radio standards in mobile radio terminal devices using a single system oscillator, a sampling rate converter converts the sampling rates from an input rate to an output rate and additionally outputs control information which is suitable for operating signal processing components. The components receiving the control information are arranged in the signal flow upstream of the sampling rate converter, on average exactly at a virtual sampling frequency. The virtual sampling pattern is mapped onto the frame of the physical operating clock by simply gating out edges of the physical operating clock. Using the control signal, a clock control device generates a masked clock that has, on average, an edge repetition rate which corresponds to the virtual sampling frequency of the samples or to an integer multiple thereof.
