| 摘要 |
The present invention relates to an arrangement (1) for an analogue compensation of a DC component (A) in an AC signal (B), comprising an estimating unit (2), adapted to produce an estimate (C) corresponding to the DC component (A), a compensating unit (3), adapted to produce a compensating signal (D) according to the estimate (C), and an adding unit (4), adapted to add the compensating signal (D) to the AC signal (B). The present invention specifically teaches the use of an analogue circuit that detects a DC drift and continuously reiterates the estimation (C) and compensation (D). <IMAGE>
