Adaptive Filter Design for Noise Reduction in Electrocardiography
Electrocardiogram is commonly used to detect abnormal heart rhythm. An electrocardiogram (ECG) records the electrical activity of the heart. ECG signal is corrupted by noise signal which restricts the correct diagnose of heart beats. Adaptive filters are used to reduce the noise signal from the ECG signal. In this paper an Adaptive filter has been designed to eliminate the noise from ECG signal...
متن کاملFilter Design for ℒ1 Adaptive Output-Feedback Controller
In this paper we exploit the connection between disturbance observer and L1 adaptive control theories. We consider L1 adaptive output–feedback control framework, for which the L1 reference controller is equivalent to the disturbance observer. Using this fact, we investigate several properties of the disturbance observer architecture, leading to various filter design methods towards verification...
متن کاملDesign of Normalized Subband Adaptive Filter for Acoustic Echo Cancellation
In hands-free telephones and teleconferencing systems, acoustic echo cancellers are required, which are often implemented by adaptive filters. In these applications, the speech input signal of the adaptive filter is highly correlated and the impulse response of the echo path is very long. These characteristics will slow down the convergence rate of the adaptive filter if the well-known normaliz...
