摘要
本文论述了电磁兼容试验中重要的电快速瞬变脉冲群试验,心电监护仪中呼吸电路如何抵消快速瞬变脉冲群(Electrical Fast Transient)的干扰;对电快速瞬变脉冲群的噪声特点进行了详细的分析,并对呼吸电路的硬件方面提出了进行改进设计方法。在实际的电磁兼容测试中表明该方法具有良好的消噪功能。
In this paper, the EFT test of the electromagnetic compatibility(EMC) and the respiratory signal of the ECG to counteract the electrical fast transient's interference are introduced. It analyzes the main constitution and principle of electrical fast Transient and gives a design of the respiratory circuit in the hardware. The EMC experiment shows its validity of counteracting EMI.
