Multiplexer is a kind of combinational logic circuit, which can be selected an in-put datum among several data and sent it to out-put port. 數據選擇器是一種能從多個輸入數據中有選擇地將一個輸入數據送到輸出端的組合邏輯電路。
A method for combinatory logic electric circuit fault detection based on feature analysis is introduced.And applies this method to the sequence circuit. 摘要介紹了常用於組合邏輯電路故障檢測的特徵分析法，並將這種方法應用於時序電路。
