Identification of a dominant signal component in a biosignal

A system for identifying a dominant signal component in a biosignal obtained from a subject, the system comprising:

• measurement means for obtaining a biosignal from a subject, the biosignal including a first signal component having a first frequency range and a second signal component having a second frequency range;
• first calculation means for determining a first indicator characterizing the probability distribution of a predefined property of the biosignal on a primary frequency band including at least part of the first frequency range;
• second calculation means for determining a second indicator indicative of the probability distribution of the predefined property of the biosignal on an auxiliary frequency band including at least part of the of the second frequency range;
• and
• identification means for identifying, which one of the first and second signal components is currently a dominant signal component in the biosignal, the identification means being responsive to the first and second calculation means.

A system for identifying a dominant signal component in a biosignal obtained from a subject, the system comprising:

• measurement device configured to measure a biosignal from a subject, the biosignal including a first signal component having a first frequency range and a second signal component having a second frequency range;
• a first calculator, responsive to the measurement device, configured to determine a first indicator characterizing the probability distribution of a predefined property of the biosignal on a primary frequency band including at least part of the first frequency range;
• a second calculator, responsive to the measurement device, configured to determine a second indicator characterizing the probability distribution of the predefined property of the biosignal on an auxiliary frequency band including at least part of the second frequency band;
• and
• identification means for identifying, which one of the first and second signal components is currently a dominant signal component in the biosignal, the identification means being responsive to the first and second calculators.

A computer program product for identifying a dominant signal component in a biosignal obtained from a subject, the computer program product comprising:

• a first program code portion configured to determine a first indicator characterizing the probability distribution of a predefined property of the biosignal on a selected primary frequency band;
• a second program code portion configured to determine a second indicator characterizing the probability distribution of the predefined property of the biosignal on a selected auxiliary frequency band;
• and
• a third program code portion configured to identify, based on the first and second indicators, which one of the first and second signal components is currently a dominant signal component in the biosignal.
