The design of the purpose is vies to answer first to solve these problems. The whole circuit can be divided into two parts: the first part is vies to answer first circuit, the second part was the timing, alarm circuit. Vies to answer first instruments have lock to save and display。 Timing, alarm circuit can not only to vies to answer first and answer problem of time for timing, and even if the two groups of vies to answer first time is a few microseconds, also can distinguish which group of preferred the answer. The whole circuit as a unit points can be divided into coding units, lock CDS yuan, adder unit, set vies to answer first time unit, and decode unit of five parts. The design of each unit required ponents is introduced in detail, and attach the circuit diagram, eventually pleted the design purpose. Key words: Vies to answer first device。 Digital circuit。 Timing。 Decoding。 Lock to save 臨沂 大學(xué)理學(xué)院 2021 屆本科畢業(yè)論文 （設(shè)計(jì)） 目 錄 1 引言 ............................................................................................................................. 1 2 設(shè)計(jì)任務(wù)目的及要求 ................................................................................................. 1 設(shè)計(jì)目的 .............................................................................................................. 1 設(shè)計(jì)要求 ............................................................................................................. 1 3 工作原理及設(shè)計(jì)方案 ................................................................................................. 2 原理框圖 .............................................................................................................. 2 設(shè)計(jì)思路 ............................................................................................................. 3 設(shè)計(jì)流程圖 ......................................................................................................... 3 設(shè)計(jì)方案 ............................................................................................................. 4 4 單元電路設(shè)計(jì)與實(shí)現(xiàn) ....................................................................................
