Abstract

Photoplethsymogram (PPG) drifts due to the changes in respiration and blood perfusion as well as external light. This hinders a proper PPG measurement. We controlled DC drifts by controlling the signal ground of PPG signals. A microprocessor-based system successfully controlled DC drifts of PPG signals.
