Abstract: A device for processing an intermediate analogue signal received from a previous system with a baseband processor. The processor includes an ordinary feedback loop for adjusting the strength of the intermediate analogue signal received from the previous system. The processor further includes a first DC offset reduction loop and a second DC offset reduction loop. A programmable filter bank and the corresponding control elements are provided so that the second DC offset reduction loop can reduce the DC offset in a flexible way. In the present invention, the DC offset can be reduced effectively and the gain training period relating to the previous system and the baseband processor can be shortened.

Abstract: A radio pre-recording apparatus and its method is proposed. In the prior art, the important portion of the radio program is usually truncated partially during recording because the recording button isn't pressed in time. For solving this problem, the radio pre-recording apparatus of the present invention has a radio frequency (RF) receiving unit; an analog/digital (A/D) converter; a buffer unit; a digital/analog (D/A) converter; a storage unit; and a control unit. The radio pre-recording method is provided for the apparatus mentioned above to prevent the important portion of the radio program from being partially truncated and to completely record the radio program.
