Summary:The present invention relates to a physiological measurement device (11) comprising a plurality of input channels (23), at least one of the input channels including a digital section configured to process at least one digital signal (d1, d2) representing an analog signal (e1, e2) present at an electrode (13) assigned to the respective channel, a signal combiner (31) configured to calculate at least one vector signal (x) from at least two processed digital signals (df1, df2). To achieve improved common-mode interference mitigation, it is proposed that the digital section of at least one input channel (23) comprise a digital filter (29) configured to filter the digital signal (d1, d2) based on a set of filter coefficients (G1, G2) and a processor (33) configured for calculating the set of filter coefficients (G1, G2) based on the vector signal (x1).
