摘要
计数器是常用的时序逻辑电路器件,文中介绍了以四位同步二进制集成计数器74LS161和异步二-五-十模值计数器74LS290为主要芯片,设计实现了任意模值计数器电路,并用Multisim软件进行了仿真。仿真验证了设计的正确性和可靠性,设计与仿真结果表明,中规模集成计数器可有效实现任意模值计数功能,并且虚拟仿真为电子电路的设计与开发提高了效率。
The counter is a sequential logic circuit part, this paper introduces the design of any modulus value counter circuit using four synchronous binary integrated counter 74LS161 and asynchronous two-five-ten modulus value counter 74LS290 as main chip, and simulation of circuit have done with Muhisim software. The Simulation verify the correctness and reliability of the design, design and simulation results show that, medium scale integrated counter can effectively achieve any modulus value counting function, and virtual simulation improve the efficiency of design and development electronic circuit.
