Method and device for signal- or spectral-adapted selection of signal or spectral sections

Abstract

Method for selecting at least one signal segment extending over a first signal section (Δ t 1 , Δ t 2 , Δ t 3 ,... ) ( { si} t E nd 1 t Start 1 , { si} t E nd 2 t Start 2 , { si} t E nd 3 t Start 3 ,... ) of a detected signal (s(t)) with the following process steps: • Determining a start time ( t Start 1 , t Start 2 , t Start 3 ,... ) of the respective first signal section (Δ t 1 , Δ t 2 , Δ t 3 ,... ) from at least one time point which corresponds to a defined first event that occurred in the signal (s(t)) or in at least one signal derivable from the signal (s(t)) or in a timer or in an external trigger signal, • Determining an end time (t End 1, t End 2, t End 3,...) of the respective first signal section (Δ t 1 , Δ t 2 , Δ t 3 ,... ) from at least one time point which belongs to a defined second event that occurred in the signal (s(t)) or in at least one signal derivable from the signal (s(t)) or in the timer or in the external trigger signal and is related to at least one first event, and • Selecting the signal waveform ( { si} t E nd 1 t Start 1 , { si} t E nd 2 t Start 2 , { si} t E nd 3 t Start 3 ,... ) of the detected signal (s(t)) in the respective first signal section ( Δ t 1 , Δ t 2 , Δ t 3 ,... ) , where the in the respective first signal sections (Δ t 1 , Δ t 2 , Δ t 3 ,... ) selected signal waveforms ( { si} t E nd 1 t Start 1 , { si} t E nd 2 t Start 2 , { si} t E nd 3 t Start 3 ,... ) of the detected signal (s(t)) with the corresponding first signal sections ( Δ t 1 , Δ t 2 , Δ t 3 ,... ) , proper start and end times ( t Start 1 , t Start 2 , t Start 3 ,..., t End 1 , t End 2 , t End 3 ,... ) on a display device (12), wherein in the respective first signal section (Δ t 1 , Δ t 2 , Δ t 3 ,... ) Deterministic and / or statistical parameters of the detected signal (s(t)) are determined and compared with associated defined reference values ​​for admissibility, and including a selection and representation of the respective first signal section (Δ t 1 , Δ t 2 , Δ t 3 ,... ) on the display device (12) only if the respective first signal section (Δ t 1 , Δ t 2 , Δ t 3 ,... ) exhibits permissible deterministic and / or statistical parameters.
