摘要
本文在普通计数器设计原理的基础上,利用集成同步加法计数器74LS160设计出一个可控的多进制计数系统。利用拨码控制电路,该系统可以分别实现7进制、9进制和79进制计数功能,从而体现出该系统的可控性、灵活性和实用性。本文借助Multisim10平台进行了仿真测试,验证了该系统的可行性。
In this paper,a controllable multilevel counting system is designed by 74LS160,which is based on the design principle of the common counter. By using the code control circuit,this system can realize the functions of level 7,9 and79,respectively. Thus,this system is controlled,flexible and practical. This paper uses the Multisim10 platform to realize the simulation and test,and the result shows that the system is feasible.
