Reprogrammable data acquisition unit to reduce aliasing effect in bioimpedance measurements

Measurement of electrical bioimpedance enables to characterize tissues and organs, to get diagnostic images, etc. A DSP-based solution for the multi-frequency and multi-channel bioimpedance measurement unit has been previously proposed and implemented. Extensions to the existing prototype data acquisition unit are discussed keeping in mind performance and cost requirements while trying to reduce the aliasing effect.
