A Bio-Impedance Signal Synthesiser (BISS) for Testing of an Adaptive Filtering System

This paper presents a design of the bio-impedance signal synthesiser (DISS), based on a model of the waveform of the electrical bio-impedance (BI) signal. To get a simple BI signal model, the shapes of the BI signal components, cardiac and respiratory, are approximated by piece-wise linear functions, which are constructed, taking into account the human physiology
