摘要

This paper presents the method for the ECG signal baseline wander reduction and prevention the analog to digital converter from saturation. The method is based on digital low pass filter in feedback loop. The digital filter estimates the ECG signal low pas variation (<0,5Hz) and via digital to analog converter feeds back the signal to reference input of instrumentation amplifier. The change of the signal voltage at the reference input is opposite in sign to the change of the signal at instrumentation amplifier input. Thus the baseline wander is significantly reduced. The method is suitable for on line processing of ECG signals, is resistant to high motion intensities and can be implemented using low power mixed signal microcontrollers.
