本文对磁心存储器磁心板中读出线上的电磁感应进行了较细致的分析。将干扰源分为静电感应和磁感应,而后再对这两种感应所产生的共式噪音和差式噪音对线路延时和干扰位置的关系加以阐明,并针对干扰源本身的相异极性可以同时出现以抵销噪音的种种措施进行了探讨。从而对过去的一些观点,如静电感应产生共式噪音,磁感应产生差式噪音以及一些δ噪音的讨论所具有的片面性得到一些修订和补充。此外,还讨论了位驱动电流有可能通过读出线对字线产生干扰,并提出其消除方案。
In this paper, a detailed analysis of the electromagnetic induction on the readout line of the magnetic core memory core board is made. The sources of interference are divided into electrostatic induction and magnetic induction, and then clarify the relationship between the common noise and the difference noise generated by the two kinds of induction on the line delay and the interference position, and at the same time, the different polarities of the interference sources can be simultaneously Various measures have been explored to offset the noise. Thus, some aspects of past discussions such as the common noise caused by electrostatic induction, the differential noise caused by magnetic induction, and some δ-noise are somewhat revised and supplemented. In addition, it is also discussed that the bit driving current may interfere with the word line through the readout line and propose the elimination scheme.
