摘　　要：在数字电路的教学中,集成计数器是一个重点无疑也是一个教学难点。本文以典型的74LS161N同步四位二进制计数器为例,用Multisim12软件对其进行功能仿真,并运用反馈清零法和反馈置数法设计十进制计数器,用同步和异步级联设计六十进制计数器来讲述任意进制计数器的设计方法,该设计方法灵活直观,可以非常直观的将电路和输出状态展现在屏幕上。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实践动手能力。In the teaching of digital circuit,integrated counter is a key is,of course,a teaching difficulty.In this paper,four typical 74LS161N synchronous binary counter,for example,use Multisim12 simulation software to function,and using the method of feedback reset and feedback for design of decimal counter method,use synchronous and asynchronous cascade design 6 decimal counter to tell the arbitrary hexadecimal design methods,the design method of flexible intuitive,can be very intuitive to circuit and output state display on the screen.Through the study of the method,can deepen students＇ understanding of counter,and the ability to practice and improve the students＇ circuit design.
