Digital circuit includes two kinds - the assembly logic circuit and the sequential logical circuit , the characteristic of the assembly logic circuit is that the output signal is only the function which enters the signal and has nothing to do with the entering state at any other moment , it has no function of memory 摘要數(shù)字電路分為組合邏輯電路和時(shí)序邏輯電路兩類,組合邏輯電路的特點(diǎn)是輸出信號(hào)只是該時(shí)的輸入信號(hào)的函數(shù),與別時(shí)刻的輸入狀態(tài)無關(guān),它是無記憶功能的。
