Bioelectric impedance measurements using synchronous sampling.
We have applied synchronous sampling to the demodulation of bioelectric impedance signals. This overcomes the need for analog demodulators in bioimpedance measurements. The sampling rate is determined by signal bandwidth, rather than by the highest frequency component before demodulation.
