An apparatus and method adaptable to desired offsets for determining an undesired offset of a signal having a maximum and a minimum state that includes: providing a peak and trough estimate of, respectively, the maximum and minimum amplitude state (51 and 53); averaging such estimates to provide a reference level that is proportional to the undesired offset (82); and controlling the peak and trough estimates whenever a comparison of the signal and the reference level is, respectively, indicative of the maximum and minimum amplitude state to thus assure adaptation to the desired offset of the signal (93). |
