顯示電路將時(shí)間“時(shí)”“分”“秒”用數(shù)字的方式顯示出來,并且需要校正電路使其準(zhǔn)確工作,還有定時(shí)和報(bào)時(shí)功能。控制較簡(jiǎn)單,沒有遙控、防電臺(tái)報(bào)時(shí)等復(fù)雜電路。調(diào)試時(shí)有的器件在理論上可行,但在實(shí)際運(yùn)行中就無法看到效果,所以得換不少器件,有時(shí)無法找出錯(cuò)誤便更換器件重新接線以使電路正常運(yùn)行。Multisim軟件有時(shí)會(huì)出問題,在理論上可行的電路在調(diào)試中未必能顯示出來,這就需要耐心、仔細(xì)地分析和解決問題,不斷地嘗試才能得出正確的答案。6 參考文獻(xiàn)[1] (數(shù)字部分)[M].:高等教育出版,[2] [M]武昌俞家山:華中科技大學(xué)出版社,[3] [M],[4][M],[5] 9的電子系統(tǒng)設(shè)計(jì)、仿真與綜合應(yīng)用[M],[6] .[M]., [7] (模擬部分)[M].:高等教育出版,7英文翻譯Topic The design and simulation of digital clockDesigners Supervising teacher Abstract digital clock ,oscillator, counter, decoding and display circuit accurately time “when” “the minute” “the second” with the digital way demonstrated that and needs the pensating circuit to cause its accurate work, but may also have fixed time and reports time the function. The research digital clock and expands its application, has the very realistic significance. This article digital clock which designs in the Multisim foundation, is by the digital integrated circuit constitution, demonstrated with the nixietubeKey word digital clock oscillator counter decoding demonstration simulation.
