搶答器是一種智力競賽常用的器件,搶答器的設(shè)計(jì)方法千差萬別,文章利用常用的數(shù)字電子器件,設(shè)計(jì)了八路搶答器電路的設(shè)計(jì)、仿真及實(shí)現(xiàn)的全過程,提出兩種可行的設(shè)計(jì)方案:方案1采用74ls373實(shí)現(xiàn)電路鎖存,74ls148實(shí)現(xiàn)電路編碼,74ls74及數(shù)碼管實(shí)現(xiàn)電路顯示;方案二采用CD4511BCN和LMC555CM集成電路及數(shù)碼管實(shí)現(xiàn)搶答器的控制和顯示。本文設(shè)計(jì)用的器件簡單,容易理解,適用于初學(xué)電子技術(shù)的人員。Answer scrambler is a common device in intelligence competition, and its design methods vary greatly. This paper designs the whole process of design, simulation and Realization of the circuit of eight-way answer scrambler by using common digital electronic devices, and puts forward two feasible design schemes: scheme 1 uses 74 ls373 to realize circuit latching, 74 ls148 to realize circuit coding,74 ls74 and digital tube to realize circuit. The second scheme uses CD4511 BCN, LMC555 CM integrated circuit and digital tube to control and display the answerer. The device designed in this paper is simple and easy to understand, and it is suitable for the beginners of electronic technology.
