Abstract: A method for producing trigger pulses in relation to a preset phase of motion proceeding with a continuously variable period, whereby pulses are accumulated, and at the same time two time intervals are successively determined within the fundamental time interval as the phase of the motion is changed by a preset value. The durations of these two time intervals and the sign of the difference between them are used to correct the number of stored pulses which are counted until a preset number is reached, which moment marks the onset of a trigger pulse. The device for effecting this method comprises a unit for determining the difference between time intervals and correcting the fundamental time interval, which is connected to a control unit, a main pulse counter and a main controlled frequency divider connected, in turn, to a pulse generator. The control unit is connected to a control pulse unit and an initial adjustment unit.
