摘要
数字逻辑电路实验故障时有发生,实验者由于查找排除方法的使用不当,经常会遇上误工费时却又不能很好解决故障的现象。本文介绍一种查找数字逻辑电路实验故障的方法—"三步分析法",使实验者不需要了解故障类型也能快速查出并及时排除故障,该方法不仅能提高实验效率,而且有助于实验者在自行排查和掌握各种故障的过程中养成良好的实验习惯,提高实验者分析问题和解决问题能力。
Failure always occurs during the digital logic circuit experiment.If operator cannot take suitable strategies to find failures,it will waste much time and be difficult to solve problems.This paper introduces a method to find failures in digital logic circuit experiment — the three-step analyzing method.By using this method,operator can find failure quickly and clear them in time without the knowledge of failure type.This method not only can improve experiment efficiency,but also is helpful to foster operator＇s good experimental habit during the process of finding and mastering kinds of failures independently and enhance operator＇s abilities of analyzing and solving problems.
