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.
我们已将同步采样应用于生物电阻抗信号的解调。这消除了生物阻抗测量中对模拟解调器的需求。采样率由信号带宽决定，而非解调前的最高频率成分。
