The invention relates to a transmission system comprising a phase-locked loop (12) which includes a phase comparator (15) for comparing an oscillator signal with a reference signal and for generating a comparison signal, and an oscillator which is provided for receiving a control signal derived from the comparison signal. The oscillator arranged as a ring oscillator (14) comprises at least one delay element (27 to 31) included in a closed circuit. At least one delay element (27 to 30) has at least two different adjustable delay times. A controller (19) is provided for setting the delay times of at least one delay element (27 to 30) in dependence on the comparison signal.
