摘要
以典型的74LS160同步十进制计数器为例,运用反馈清零法和反馈置数法设计六十进制计数器来讲述任意进制计数器的设计方法;用Proteus软件进行仿真设计,该设计方法灵活直观,可以在缺少硬件的条件下能很快对所设计电路的正确性进行验证;通过万能板完成电路制作,进一步验证理论设计的正确性。通过该方法的学习,可加深学生对计数器的理解,提高学生的电路设计和动手能力。
Taking the typical 74LS160 synchronous decimal counter as an example and using the methods of feedback clearing and feedback resetting to design 60 number scale counter, the paper explains the methods of designing arbitrary number scale counter. By the use of the software Proteus, it carries out the simulation design, which is flexible and intuitive and can verify the correctness of the designed circuit in the absence of the hardware. Then complete the circuit through universal board to further verify the correctness of the theoretical design. Learning this method can enhance the students＂ understanding of the counter and improve their ability of designing the circuit.
