詳細介紹組合邏輯電路的特點與組成
1.組合的特點
If a digital circuit, the circuit's output at any one time, just decided that the time of the input circuit, but hasnothing to do with the circuit to its original state, then the sub-circuit is called the combinational logic circuits, referred to as combinational circuits. If the combinational logic circuit is only one output, called the single-output combinational logic circuit; if more than one output, called the multi-output combinational logic circuit
如果一個數(shù)字電路，電路的任一時刻的輸出，剛剛決定，該輸入電路的時間，但已無關(guān)的到其原始狀態(tài)的電路，則子電路稱為組合邏輯電路，稱為作為組合邏輯電路。如果組合邏輯電路只有一個輸出，稱為單輸出組合邏輯電路;如果超過一個輸出，稱為多輸出組合邏輯電路
2.組合邏輯電路的組成
組合邏輯電路的組成方框圖如圖1所示。它有n個輸入端，m個輸出端，Xi為輸入邏輯變量，Yi為輸出邏輯變量。輸出變量Y1，Y2，...，Ym是輸入變量X1、X2，…，Xn的函數(shù)，即：
Y1=f1(X1,X2,…,Xn)
Y2=f2(X1,X2,…,Xn)
┇
Ym=fm(X1,X2,…,Xn)
