Abstract
The invention concerns a method of dividing a digital signal representing physical quantities, characterised in that it includes the steps of: determining (E1) an initial partitioning of the signal, displaying (E3, E4) a representation of the signal and the previously determined signal partitioning, acquiring (E7) at least one partitioning modification parameter, modifying (E7) the partitioning of the signal.

Method of dividing a digital signal representing physical quantities, characterised in that it includes the steps of:
- determining (E1) an initial partitioning of the signal,
- displaying (E3, E4) a representation of the signal and the previously determined signal partitioning,
- acquiring (E7) at least one partitioning modification parameter,
- modifying (E7) the partitioning of the signal.
Method of dividing a digital signal representing physical quantities, characterised in that it includes the steps of:
- determining (S1) at least one area of interest in the signal,
- determining (S20) an initial partitioning of the signal, including partitioning areas,
- modifying (S22, S24, S26) the partitioning of the signal according to said at least one area of interest and a predetermined criterion.
Device for dividing a digital signal representing physical quantities, characterised in that it has:
- means (31) of determining an initial partitioning of the signal,
- means (310) of displaying a representation of the signal and the previously determined signal partitioning,
- means (31) of acquiring at least one partitioning modification parameter,
- means (31) of modifying the partitioning of the signal.
