Method for a runtime measurement of a signal between two events. A phase shift between the signal on the occurrence of a first event and the signal on the occurrence of a second event is determined, and to an arrangement for performing the method has the underlying object of providing a runtime measurement of a signal between a first event and a second event that can be carried out with a high accuracy, at a high speed, and with a low computational effort. A modulation signal is generated whose phase position is determined as a first signature for the occurrence of the signal in the first event. The phase position of the modulation signal is determined as a second signature for the occurrence of the signal in the second event; and in that the runtime is determined as a difference of the phase positions of the first and second signatures.
