Abstract
A biopotential signal acquisition system including an analog readout unit configured to receive an analog biopotential signal, which may be acquired from at least one electrode attached to a body; and to extract an analog measured biopotential signal and an analog reference signal. The system also includes an ADC unit configured to provide a digital version of the analog measured biopotential signal and the analog reference signal, a digital filter unit configured to calculate a digital motion artifact estimate based on the digital version of the measured biopotential signal and the reference signal. The system further comprises a reference signal processing unit configured to convert the reference signal into a new reference signal being provided to the digital filter unit based on the correlation between the measured biopotential signal and the reference signal.
