Processed signals and theirs spectra. From top: preprocessed EGG4 Hz (0.15–0.5 Hz) signal (left) and its spectrum (right), classical EGG (0.015–0.15 Hz) and its spectrum, ExEGG (0.015–0.5 Hz) after adaptive filtering and its spectrum, AfEGG (0.015–0.15 Hz) and its spectrum, derived respiration signal (EDR) and its spectrum, thermistor derived respiration signal (TDR) and its spectrum. The EDR and TDR signals are normalized to the unity.
