The present invention provides a multi-channel physiological signal measure system, which includes a signal input module, a pre-processing module, and a digital processing module. The signal input module is used to receive a plurality set of physiological signal. The pre-processing module includes a plurality of pre-amplified units, wherein each pre-amplified unit is used to amplify the corresponding received physiological signal and output an amplified physiological signal accordingly. The digital processing module receives at least one set of the amplified physiological signal using a time division multiplex and multiplexer (TDM) method. The digital processing module converts the received amplified physiological signal and output the digital physiological signal accordingly. Further, the digital signal includes at least one set of physiological signal, and users thereby can simultaneously extracting the multi-band physiological signal from the amplified physiological signal.本發明提供一種多通道生理訊號量測系統,包括訊號輸入模組、前置處理模組以及數位處理模組。其中,訊號輸入模組用以接收複數組生理訊號。前置處理模組具有複數個前置放大單元,每一個前置放大單元會接收一組對應的生理訊號,並提供訊號放大處理以輸出一組生理放大訊號。數位處理模組以分時多工方式接收至少一組生理放大訊號,並對接收到的生理放大訊號提供訊號轉換以輸出數位生理訊號。由於數位生理訊號中包含了至少一組的生理訊號,故使用者可同時從中得到多頻段的生理訊號。1...多通道生理訊號量測系統10...訊號輸入模組110...生理感測器120...訊號傳輸通道130...參考電壓傳輸通道20...前置處理模組210...前置放大單元30...數位處理模組40...終端裝置401...人機操作介面
