Abstract(in English) A filter was already proposed to filter interferences on impedance cardiographic signals, named scaled Fourier linear combiner (SFLC). At a first look at the filter power spectrum, one may believe that this filter can eliminate also the bias. In this work, we will study the effect of bias and spectral overlap on the SFLC, and its implication on filtering impedance cardiographic signals. We also have carried out some experiments to study these problems. We found that the bias alters the weights behavior, and therefore the filter output. We also discuss solutions to the problem of spectral overlap.
