전기 임피던스를 측정할 때 외부 간섭을 제거하기 위한 대역확산 기술의 적용 = Rejecting Interference in Electrical Impedance Measurements by Using Spread Spectrum Technique

다국어 초록 (Multilingual Abstract)

When we measure electrical impedance of a small object, such as an electronic component, external interference or jamming signal can be rejected by shielding the object. However, when we measure impedance of a large object, such as a human body, shielding is not easy and severe error due to the external interference could be introduced. In this paper, spread spectrum technique applicable to bioimpedance measurements for rejecting external interference without shielding is introduced. The improvement in signal-to-jamming ratio by the spread spectrum technique was experimentally confirmed.
