摘要
电子仪器"接地"与"共地"是抑制干扰,确保人身和设备安全的重要技术措施。在电子电路测量中,元器件及各部分电路接地的合理与否对电路性能影响很大。本文分析了电子电路实验中的共地问题,并以实例说明了共地的必要性。
electronic devices ＂grounded＂ and ＂total land＂ is the interference suppression to ensure the safety of persons and equipment important technical measures. In electronic circuits, components or circuit ground is a great impact on circuit performance. This paper analyzes the problem, and illustrated the need for a total land in electronic circuit experiment.
