METHOD AND CIRCUIT ARRANGEMENT TO REDUCE A DC-OFFSET
To reduce the DC-offset in bursts (B 1 , B 2 ) of a digital signal (S 1 ), some samples of one of the digital bursts (B 1 ) which have no predetermined value are averaged by an averager (AV) resulting in a correction value (CV). Meanwhile the samples of this digital burst (B 1 ) are temporarily stor...

| Zusammenfassung: | To reduce the DC-offset in bursts (B
1
, B
2
) of a digital signal (S
1
), some samples of one of the digital bursts (B
1
) which have no predetermined value are averaged by an averager (AV) resulting in a correction value (CV). Meanwhile the samples of this digital burst (B
1
) are temporarily stored in a memory (MEM
1
). The DC-offset correction value (CV) calculated by the averager (AV) is then subtracted from the samples of the digital bursts (B
1
, B
2
). In this way, he dynamic range of the samples is reduced significantly. |
