Abstract :
Multi-channel data-acquisition devices are used often in biomedicine to measure properties of organs/tissues. A DSP-based solution for a multi-frequency measurement unit has been proposed and implemented. In this paper, extensions to the existing prototype data acquisition unit are discussed. The extensions were designed to allow to reduce the aliasing effect.
