Abstract
A non-integral delay circuit for delaying a digital signal by a selectable fraction (.delta.) of a sampling period of the digital signal includes a first differentiator (S3) to obtain a first differential signal (F1) having a first phase characteristic with respect to the digital signal, a second differentiator (D) to obtain a second differential signal (F2) having a second phase characteristic with respect to the digital signal, the first and second phase characteristics differing from each other, a mixer (MIX) for combining the first (F1) and second (F2) differential signals in dependence on the selectable fraction (.delta.) to obtain a phase-adjusted correction signal, and an adder (A9) which adds a product (M3) of the selectable fraction (.delta.) and the phase-adjusted correction signal to the digital signal, to obtain the digital signal delayed by the selectable fraction (.delta.) of the sampling period of the digital signal.
