Abstract
A patient monitoring system may receive a physiological signal such as a photoplethysmograph (PPG) signal. The PPG signal may include a pulsatile component that functions as a carrier signal and an amplitude modulation component that represents respiration information. The patient monitoring system may move the amplitude modulation component to a baseline component of the PPG signal. Respiration information may be calculated based on the amplitude modulation component.
