Abstract

The performance of a differential synchronous demodulator is presented. This demodulator is part of an electrical impedance tomography system developed by our group. In addition a technique for common-mode correction instead of common-mode feedback is proposed. A series of measurements as a function of the common-mode signal is given.

摘要

介绍了一种差分同步解调器的性能。该解调器是我们团队开发的电阻抗断层成像系统的一部分。此外，还提出了一种用于共模校正而非共模反馈的技术。给出了一系列作为共模信号函数的测量结果。
