Abstract
Physiological parameter(s) are determined from a biopotential having one or more signal distorting elements. The method may involve suppressing one or more signal distorting elements may be from an acquired biopotential signal by decomposing the acquired biopotential signal, identifying the one or more signal distorting elements present in the acquired biopotential signal and reconstructing the decomposed biopotential signal without the one or more identified signal distorting elements. The method may involve determining a physiological parameter by analyzing decomposed elements of an acquired biopotential signal.

A method for suppressing one or more signal distorting elements from a biopotential signal indicative of a biopotential at a location on a body of a subject, the method comprising:
- acquiring the biopotential signal from the body of the subject using a plurality of electrodes;
- and
- digitally processing the biopotential signal, the digital processing comprising:
- decomposing the biopotential signal into a plurality of subsignals;
- identifying the one or more signal distorting elements in the plurality of subsignals;
- and
- reconstructing the biopotential signal using the plurality of subsignals, the reconstructing comprising removing the one or more signal distorting elements from the plurality of subsignals.
A system for suppressing one or more signal distorting elements from a biopotential signal indicative of a biopotential at a location on a body of a subject, the system comprising:
- a plurality of electrodes couplable to a tissue surface of the subject;
- and
- a digital signal processor, the digital signal processor configured to:
- decompose the biopotential signal into a plurality of subsignals;
- identify the one or more signal distorting elements in the plurality of subsignals;
- and
- reconstruct the biopotential signal using the plurality of subsignals,
- the reconstructing comprising removing the one or more signal distorting elements from the plurality of subsignals.
A method for determining a physiological parameter based on a biopotential signal indicative of a biopotential at a location on a body of a subject, the method comprising:
- acquiring the biopotential signal from the body of the subject using a plurality of electrodes;
