摘要
用反馈清零法或预置数法皆可以利用中规模集成计数器实现任意进制计数器的设计,通过硬件实验可以由数码管显示数值验证2种方法的正确性,但是很难直观显示2种方法的本质区别。利用Multisum软件中丰富的虚拟仪器进行仿真,不仅可以验证2种设计方法的正确性,且可以弥补目前教学过程中硬件方面的不足,形象地显示2种方法之间的本质区别。通过理论与实践紧密结合,助于加深对理论知识的理解和重点难点问题的掌握。
The method of setting-numerical value by beforehand and setting-zero by feedback may accomplish the design of number systenm discretional counter, the correctness can be validated through the display of number in experiment, but it can＇t display the essential difference. The shortage of hardware can be solved by the simulation of Multisim, the essen- tial difference can be display visually through wave-form of counter, moreover, the combination of theory and practice can help students understand the theory and mastery the emphases and the difficulties.
