Procedure for the determination of a numerical value for the time duration of a signal pulse shape that device for performing a method of this type is repeated periodically, and.

摘要

Method for determining a numeric value which characterizes the pulse rate of a signal (68) pulse shaping, which is periodically repeated, with the following steps: a) At time intervals the duration (T) of the period is determined signal. b) time intervals determined as magnitude (t; t ') characteristic for this signal (68) or the duration (t) of a pulse (69) or duration (t') time between two successive pulses. c) From the duration (T) of the period and the magnitude (t; t ') feature the numerical value (NorPVal) characterizing the pulse rate signal (68) is determined. Determining the magnitude (t or t '') feature according to the magnitude of a numeric value (NorPVal) determined in at least one preceding determination of the numeric value (Figure 20).
