Abstract
An apparatus and method for measuring a biosignal that include generating a control signal for processing the biosignal based on an obtained replication signal or a sensed motion of the subject.
Claims15
An apparatus for measuring a biosignal, the apparatus comprising:
- a biosignal interface configured to measure the biosignal;
- a dummy interface configured to detect a dummy signal;
- a processor configured to
- obtain a replication signal from the biosignal using the biosignal interface and the dummy interface,
- wherein the replication signal is proportional to a motion artifact in the biosignal;
- determine, based on the replication signal, an artifact degree of the motion artifact;
- compare the artifact degree to a threshold to generate a comparison result;
- generate, based on the comparison result, a control signal for controlling adaptive filtering of the biosignal to reduce the motion artifact;
- and
- process the biosignal based on the control signal.
