【摘要】 针对传统数字电子技术实验项目在学生设计与实现过程中容易出现故障,对经常出现的问题进行提炼总结,提出TTL电平反推法,根据输出的实验现象一步一步向前反推,找出对应的原状态的致使条件,对的保留,不对的继续反推前一级,找出错误的根源。通过教学实践,学生可以具备自行解决数电实验项目中常出现问题的能力,证明TTL电平反推排错法在数电实验教学应用中具有可实施性。更多还原

【Abstract】 For these student failures in the design and implementation of traditional digital electronic technology experiment program, refine and summarize common problems, the TTL anti-slip method is proposed. Step forward and backward according to the experimental phenomenon of output, To find the conditions that correspond to the original state. Retain the right, continue to push forward the wrong level, find the root of the error. Through teaching practice, the students can have the ability to solve problems frequently in electrical test projects, it is proved that TTL electric flat reverse dislocation method can be implemented in several experiment teaching applications.更多还原
