<p>The invention relates to an offset determination apparatus (107) and a method for correcting an offset by supplying a switch-off signal (TX_On) outside a predefinable measuring range (407, I) of time-expanded sampling values (421b, 421c, 421d, 421e) of a reflection signal (C), which switch-off signal can deactivate a transmitter device (302) at least intermittently in order to generate a predefinable quiescent range (408, II) within the time-expanded sampling values (421b, 421c, 421d, 421e) of the reflection signal (C) and in that, by evaluating at least one sampling value (421b, 421c, 421d, 421e) of the time-expanded sampling values which is determined within the quiescent range (408, II), a value of an amplitude offset (406) of the time- expanded sampling values (421b, 421c, 421d, 421e) of the reflection signal (C) from a normal value (403) is determined and is supplied at an output (210a, 210b) of the offset provision device (208).</p> |
