This study presents a technique for separation of Heart Sound Signal (HSS) from Lung Sound Signal (LSS) using Adaptive Line Enhancer (ALE) with Least Mean Square (LMS) algorithm with real time recorded sound signal. While recording lung sounds, an incessant noise source takes place owing to heart sounds. This noise source severely contaminates the breath sound signal and interferes in the analy...

Fetal Heart Rate signal is an objective index which reflects the physiological activity of foetus heart electricity, The abstraction and processing of the signal of foetus' rhythm of the heart enclose the key technology which the foetus guards in childbirth period. For dealing with this kind of nonsteady random signal of foetus' rhythm of the heart. Through adjusting weight value the adaptive f...

ECG signal is able to identify different kind of heart disease. One of the critical heart problem is the abnormal heart beat behavior during sleep. This problem is recognized as sleep apnea. In this work, a feature adaptive model is presented for Sleep apnea identification. To generate the effective signal features, the spectral subtraction and DWT methods are applied at earlier phase. After ge...

We describe a simple model of cardioventilatory coupling in which a hypothetical inspiratory pacemaker is stimulated by a signal related to cardiac action. At suitable values for the control variables (cardiac signal magnitude, heart rate, inspiratory pacemaker rate and inspiratory rate variability), the model was found to: (1) replicate all clinically described patterns of coupling; (2) predic...
