| Abstract: | In this paper,a kind of real time signal acquisition and saving system based on LabVIEW and signal preprocessing method for ECG and heart sound was proposed.Firstly,an analog sampling circuit design was introduced.Secondly,the software design for real time data acquisition,store and redisplay by using LabVIEW and NI-DAQ were described.Finally,a signal preprocessing method,including de-noising the ECG signal by the means of Wavelet and extracting the envelope of the heart sound signal by means of normalized average Shannon energy was put forward. |
