摘要： A biosignal monitoring system (100) for reducing a motion artifact from at least one biopotential electrical signal input (1, 2), comprises: a signal processing module (10), a motion artifact extraction module (9) and a subtraction module (11). The motion artifact extraction module (9) and the signal processing module (10) receive the biopotential electrical signal input (1, 2) and the subtraction module (11) receives both an extracted signal from an output (3, 4) of the motion artifact extraction module (9) and a biopotential electrical signal from an output (5, 6) of the signal processing module (10). The subtraction module (11) is configured for subtracting the extracted signal from the biopotential electrical signal. The motion artifact extraction module (9) is implemented as analog domain electronic circuit and comprises a filter network, configured for attenuating differential mode signals of the biopotential electrical signal input (1, 2) from a first frequency (F1), and passing a representation of the motion artifact signal from the biopotential electrical signal input (1, 2) up to a second frequency (F2) at the output (3, 4) of the motion artifact extraction module (9).
