This invention relates to a brainwave signal analysis device.It includes a wave detection unit for detecting the brain wave signal of the subject.A signal processing unit and a display unit；The signal processing unit includes a first operation unit,1. Second operation unit,1. The third operation unit,1. Drawing unitA database and an output unit,It is used to process brain wave signals and output them to the drawing unit.Then the data stored in the database are compared and analyzed.Finally, a detection information is output to the display unit through the output unit.In this way,This creation can be used to judge whether the subject has brain lesions.本創作有關於一種腦波訊號分析裝置，係包括一偵測受測者腦波訊號腦的波偵測單元、一訊號處理單元以及一顯示單元；其中訊號處理單元又包括一第一運算單元、一第二運算單元、一第三運算單元、一繪圖單元、一資料庫以及一輸出單元，其係用以處理腦波訊號並輸出至繪圖單元，再經由資料庫所儲存之資料進行比對與分析，最後透過輸出單元輸出一檢測資訊至顯示單元；藉此，本創作可用以判斷受測者是否患有腦部病變。
