System and method for acquisition of biopotential signals with motion artifact reduction in real time operation |
摘要 |
The invention relates to a biopotential signal acquisition system (100) comprising: an analogue readout unit (10) configured to receive an analogue biopotential signal (BS1) and to extract an analogue measured biopotential signal (BS2) and an analogue reference signal (REF); an ADC unit (20) configured to provide a digital version of the analogue measured biopotential signal (DBS2) and the analogue reference signal (DREF); a first digital filter unit (30) comprising a cascaded integrator-comb filter (32) configured to provide a first digital filtered version (DBS2', DREF') of the digital measured biopotential signal (DBS2) and the reference signal (DREF); and a second digital filter unit (40) configured to calculate a digital motion artifact estimate (MA) based on said first digital filtered version signals (DBS2', DREF'). The invention further relates to an electronic device and a method for acquisition of biopotential signals. |
