1、計(jì)數(shù)器概述計(jì)數(shù)是一種最簡(jiǎn)單基本的運(yùn)算，計(jì)數(shù)器就是實(shí)現(xiàn)這種運(yùn)算的邏輯電路，計(jì)數(shù)器在數(shù)字系統(tǒng)中主要是對(duì)脈沖的
個(gè)數(shù)進(jìn)行計(jì)數(shù)，以實(shí)現(xiàn)測(cè)量、計(jì)數(shù)和控制的功能，同時(shí)兼有分頻功能，計(jì)數(shù)器是由基本的計(jì)數(shù)單元和一些控制門所組成，計(jì)數(shù)單元?jiǎng)t由一系列具有存儲(chǔ)信息功能的各類觸發(fā)器構(gòu)成，這些觸發(fā)器有RS觸發(fā)器、T觸發(fā)器、D觸發(fā)器及JK觸發(fā)器等。計(jì)數(shù)器在數(shù)字系統(tǒng)中應(yīng)用廣泛，如在電子計(jì)算機(jī)的控制器中對(duì)指令地址進(jìn)行計(jì)數(shù)，以便順序取出下一條指令，在運(yùn)算器中作乘法、除法運(yùn)算時(shí)記下加法、減法次數(shù)，又如在數(shù)字儀器中對(duì)脈沖的計(jì)數(shù)等等。
在數(shù)字電子技術(shù)中應(yīng)用的最多的時(shí)序邏輯電路。計(jì)數(shù)器不僅能用于對(duì)時(shí)鐘脈沖計(jì)數(shù)，還可以用于分頻、定時(shí)、產(chǎn)生節(jié)拍脈沖和脈沖序列以及進(jìn)行數(shù)字運(yùn)算等。但是并無(wú)法顯示計(jì)算結(jié)果，一般都是要通過(guò)外接LCD或LED屏才能顯示。
