External
Module
External dll 操作流程
External DLL
可以連接使用者撰寫C#, C++, VB的.DLL，如上例，Visual Signal
External DLL利用C# DLL透過網路連接Yahoo
Stocks，並選擇某一段時間及某股票，上圖為Visual
Signal展示台積電股價K線圖，最後並可利用Visual
Signal再進行各種展示及運算。
DAQ Module
DAQ for AI card
TD1A - 微型無線多頻道生理記錄儀
DAQ 模組目前支援National
Instruments全系列AI卡 及
TD1A無線生理擷取儀，幫助使用者直接將外界物理訊號擷取至Visual
Signal進行訊號展示，選擇正確訊號，最後進行運算，不需要透過其他另存及轉檔，才能將資料匯入Visual
Signal。
