A electronic apparatus including sensing unit and processing unit is provided. The sensing unit is adapted to generate a biological electric signal. The processing unit electrically connected to the sensing unit converts the signal intensity of points of the signal into sequence S 1= and convert the sequence S1 into . Processing unit obtains a group of subsequence with an arranging length ( m+1), wherein 1≤ k≤( n-1- m) processing unit calculates the repeated times of every kinds of arrangement in the group of subsequences , and define characteristic arrangement in the group of subsequences , and compare the repeated time of the characteristic arrangement with a standard threshold, so as to distinguish a physical information of the biological electric signal.一種電子裝置,其包括檢測單元以及處理單元。檢測單元適於產生一生物電性訊號。處理單元電性連接至該檢測單元,其中處理單元適於接收生物電性訊號,並將生物電性訊號中的多個點的訊號強度記錄為序列 S 1= ,並將序列 S 1轉換為序列 。處理單元以至少一排列長度( m+1)自序列 S 2取得一組子序列 ,且1≤ k≤( n-1- m);處理單元統計這組子序列 D k中每種排列方式的出現次數,並自這組子序列 D k的排列方式中決定一特徵排列方式,並比較特徵排列方式在這組子序列 D k的重複次數與一標準閥值,進而分辨該生物電性訊號背後所攜帶的生理資訊。A‧‧‧部位50‧‧‧待測者100‧‧‧電子裝置110‧‧‧檢測單元120‧‧‧處理單元130‧‧‧濾波單元140‧‧‧訊號放大單元150‧‧‧類比數位轉換單元160‧‧‧輸出單元
