Abstract

In a method and device for determining the spacing between first and second sequences of signal values, first and second successive signal values of the first sequence have assigned thereto a third signal value of the second sequence, the third signal value being located temporally or spatially between the first and second signal values of the first sequence. A first spacing value is determined based on a mixing value from the first and second signal values, a second spacing value between the mixing value and the third signal value, an interval width value based on the width of an interval defined by the first and second signal values, and mapping of the second spacing value onto the first spacing value using the interval width value such that a mapping curve has at least two segments with different slopes, where the slope of the curve, at least in segments, is shallower for second spacing values smaller than the interval width value than for second spacing values larger than the interval width value, and such that for at least one second spacing value smaller than the interval width value, the resulting first spacing value is smaller than this second value. A plurality of first sp…
