Abstract
A time-discrete signal is delayed by a selectable fraction (.delta.) of a sampling period of the time-discrete signal. First (F1) and second (F2) differential signals having mutually different phase characteristics are derived from the time-discrete signal and are subsequently combined (MIX) dependent upon the selectable fraction (.delta.) to obtain a phase-adjusted correction signal. The product of the selectable fraction (.delta.) and the correction signal is added to the time-discrete signal to obtain a time-discrete signal which has been delayed by the selectable fraction (.delta.). The second differential signal is obtained by means of a differentiator with asymmetric coefficients in order to optimise the transfer characteristic for .delta.=0.5.
