  • System and method for improving signal to noise ratio for high frequency signal component
    Patent number: 9294121
    Abstract: An apparatus and method for improving signal to noise ratio of a physiological signal is provided. At least one sensor senses the analog data signal, the analog data signal having a first component including ECG data and a second component including ancillary data. A converter is coupled to the at least one sensor that automatically converts the analog data signal into a digital data signal and decimates the digital data signal from a first sample rate to a second sample rate.
    Type: Grant
