METHOD AND CIRCUIT ARRANGEMENT TO REDUCE A DC-OFFSET |
摘要 |
To reduce the DC-offset in bursts (B1, B2) of a digital signal (S1), some samples of one of the digital bursts (B1) which have no predetermined value are averaged by an averager (AV) resulting in a correction value (CV). Meanwhile the samples of this digital burst (B1) are temporarily stored in a memory (MEM1). The DC-offset correction value (CV) calculated by the averager (AV) is then subtracted from the samples of the digital bursts (B1, B2). In this way, he dynamic range of the samples is reduced significantly.
