Abstract
To reduce the DC-offset in bursts (B B ) of a digital signal (S ), some samples of one of the digital bursts (B ) 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 ) are temporarily stored in a memory (MEM ). The DC-offset correction value (CV) calculated by the averager (AV) is then substracted from the samples of the digital bursts (B B ). In this way, the dynamic range of the samples is reduced significantly.
