[Metrologic aspects of interactions of probing currents with the impedance of biological objects in the system of temporary channel separation in rheographic equipment].
The interaction of the optimal shape probing current with the bio-object electrodes system impedance in the channels time division mode using the rheographic instruments has been analysed. It was shown that the present method of multichannel bioimpedance measurements is accompanied with additional noises which result from the transient process in the probe Scheme. Taking into consideration the spectrum characteristics of the useful signal and the mentioned above noise a simple and rather effective way of elimination their destabilizing action has been achieved.
