基于Multisim的计数、译码与显示电路

摘要

介绍了利用译码驱动器74LS47(或74LS48)、十进制可逆计数器74LS192集成芯片,配合数码管、电源、开关、字信号发生器、逻辑分析仪等器件,设计实现了计数、译码与显示电路,并用Multisim虚拟仿真软件对电路进行了仿真与分析.在虚拟仿真后,再搭建硬件电路进行实物实验,通过虚实结合,优势互补,全面提高实践技能与创新能力.%This paper describes the use of decoding driver 74LS47 (or 74LS48), decimal reversible counter integrated chip 74LS192, with digital tube, power supply, switch, word generator, logic analyzer and other devices, with all the devices this counting, decoding and display circuit have been designed, and the use of Multisim virtual simulation and analysis have been made on the circuit simulation software. After the virtual simulation, build the hardware circuit to carry out the physical experiment. Through the combination of virtual and real experiment, we can complement each other's advantages and comprehensively improve the practical skills and innovative ability.
