【正文】 題目：數(shù)字搶答器畢業(yè)論文信息工程學(xué)院 電子信息工程 學(xué)號(hào)：學(xué)生姓名：指導(dǎo)老師：起訖時(shí)間： 一、摘要：數(shù)字搶答器由主體電路與擴(kuò)展電路組成。優(yōu)先編碼電路、鎖存器、譯碼電路將參賽隊(duì)的輸入信號(hào)在顯示器上輸出；用控制電路和主持人開(kāi)關(guān)啟動(dòng)報(bào)警電路，以上兩部分組成主體電路。通過(guò)定時(shí)電路和譯碼電路將秒脈沖產(chǎn)生的信號(hào)在顯示器上輸出實(shí)現(xiàn)計(jì)時(shí)功能，構(gòu)成擴(kuò)展電路。經(jīng)過(guò)布線(xiàn)、焊接、調(diào)試等工作后數(shù)字搶答器成形。關(guān)鍵字： 搶答電路 定時(shí)電路 報(bào)警電路 時(shí)序控制 SummaryThe figure vies for the answering device by the subject circuit and expands the circuit to make up . Have priority in code circuit , latch , decipher circuit and export the input signal of the entrant team on the display。 Starting the warning circuit with the control circuit and host39。s switch, two the abovementioned parts make up the subject circuit. Through timing circuit and decipher second signal function while outputs and realizes counting on the displaying that pulse produce circuit, form and expand the circuit. Through connect up , weld , debug figure vie for answering device take shape after the work.Key word： Vie for answering the circuitTiming circuit Warning circuitTime sequence controlling二、目 錄摘要………………………………………………………………………………… ⅠAbstract………………………………………………………………………………ⅡBR一、
