16路抢答器电路改进设计

Improved Design for Circuit of 16-route Answering Machine

针对李燕等基于74LS系列数字集成电路的《多路抢答器设计》之不足,提出了16路抢答器电路的3种改进设计方案。该电路可以将最先抢答者的编号从1-16正确显示出来。采用Multisim 11软件仿真实验证明,其电路设计合理,方案可行。

To the deficiency of Li Yan＇s design of Multi - route Answering Machine based on 74L5 - series IC, this paper brings forward three schemes of improved design for circuit of 16 - route answering machine. The number of the first player can be orderly displayed from 1 to 16 correctly. Finally, the circuits have been tested in the environment of Multisim 11, and the experimental results prove that these schemes are correct and feasible.
