本文以151-3型计算机运控分机调试为背景,从可靠性角度出发,对如何合理使用高速TTL电路构成可靠的高速机器系统,分析研究了几个问题。它们是:电路的“沉睡”问题;信号的传输与匹配问题;电路的“炎脉冲下跳展宽”问题;线间感应干扰问题;电路测试问题。本文不研究器件本身的可靠性。
Based on the commissioning of 151-3 computerized control extension, this paper analyzes how to make use of high-speed TTL circuits to form a reliable high-speed machine system from the reliability point of view, and analyzes several problems. They are: circuit “sleeping” problem; signal transmission and matching problems; circuit “pulse stretching under the jumper” problem; interline sensing interference problems; circuit testing problems. This article does not study the reliability of the device itself.
