摘要：

A DSP-based solution for the 16-bit multi-frequency and multi-channel bio-impedance measurement unit, using of under--sampling discrete Fourier' transform (DFT, has been proposed and realized The unit has multiple outputs (8) and inputs (4), and operates at frequencies up to 5 MHz. Some performance matters of the proposed solution are discussed, mostly related to noise aliasing and accuracy depending on modulation signal frequency.
