Abstract :
Measurement of electrical bioimpedance enables to characterize a state of tissues/organs, to get diagnostic images, to find hemodynamical parameters, etc. In this paper we consider a digital multichannel bioimpedance analyser developed for monitoring of the state of a working heart. The signal-processing task, which must be solved in this analyser, is described and some proposed alternative algorithmic and hardware solutions of this task are considered and compared
