Description: 
"       該圖是由3個JK觸發(fā)器構成的，各級觸發(fā)器受同一時鐘CP控制為一同步時序電路，X為控制輸入信號。這個電路實現(xiàn)了計數(shù)的功能，計數(shù)的對象是時鐘CP的個數(shù)。當X=0時，電路中的狀態(tài)代碼與輸入CP個數(shù)成加一計數(shù)關系。在一個循環(huán)周期內共有6個狀態(tài)，也就是可以計數(shù)到6個CP脈沖，我們稱此時計數(shù)的長度（模長）為6。輸出Z可以看做是計數(shù)時的進位信號，當輸入5個CP，電路中的代碼是101（5）時，Z=1，當輸入第6個CP，電路回到000狀態(tài)（初始狀態(tài)），Z由1變0，產生進位信號。當X=1時，可以看出，電路也完成計數(shù)功能，不過計數(shù)模長為5并且初態(tài)為001。"
