基于Multisim心形流水灯电路的设计与仿真

【摘要】 时序逻辑电路的设计是数字电子技术课程的重点和难点。传统的时序逻辑电路教学内容主要围绕计数器、脉冲发生器展开,缺少实用性和趣味性,很难激发学生的学习兴趣。针对这一问题,文章设计了一种心形流水灯电路,该电路通过移位寄存器74LS194N实现,可设置多种灯光流水模式。用Multisim软件对电路进行仿真分析和设计验证,获得预期实验结果。将该电路应用于数字电子技术课程的教学中可以有效提升课程的实用性和高阶性。更多还原

【Abstract】 The design of the sequential logic circuit is the key and difficult point of digital electronic technology course.The traditional teaching content of sequential logic circuit mainly focuses on counter and pulse generator, which lacks practicality and interest, thus difficult to be used to stimulate students’ interest in learning. To solve this problem, a heart-shaped flowing water light circuit is designed in this paper. It is realized by shift register 74 LS194 N, and has a variety of flowing water light display modes. The circuit is simulated and verified by Multisim software, and the expected experimental results are obtained. The application of the circuit in the teaching of digital electronic technology can effectively improve the practicality and level of the course.更多还原
