本文就数字逻辑电路的调整试验及工作中发现的一些干扰现象进行了理论分析,并介绍了所采取的抑制措施。作者指出干扰进入数字逻辑电路常常通过辐射和传导两种途径。辐射是通过电磁波发射进入数字电路的;传导是通过数字电路的电源或 In this paper, the adjustment experiments of digital logic circuits and some interference phenomena found in the work are theoretically analyzed, and the measures to be taken are introduced. The authors point out that interference into digital logic often passes both ways of radiation and conduction. Radiation is emitted into the digital circuit by electromagnetic waves; conduction is through the digital circuit’s power supply or
