Single-Chip Implementation of Level-Crossing ADC for ECG Sampling
Traditional ADCs (Analog-to-Digital Converters) acquire samples at regular intervals TS at a sample rate fS=1/TS and needs to adhere to the Nyquist sampling theorem, i.e., fS>2 × fB, where fB is the signal’s bandwidth [1]. Due to the periodic nature of traditional ADCs, they are sometimes referred to as synchronous ADCs [2,3]. Synchronous ADCs are characterized by a periodicity in time and equi...

متن کاملFeature extraction from a novel ECG model for arrhythmia diagnosis.
Feature extraction is a crucial aspect of computer-aided arrhythmia diagnosis using an electrocardiogram (ECG). A location, width and magnitude (LWM) model is proposed for extracting each wave's features in the ECG. The model is a stream of Gaussian function in which three parameters (the expected value, variance and amplitude) are applied to approximate the P wave, QRS wave and T wave. Moreove...
متن کاملReal Time ECG Feature Extraction and Arrhythmia Detection on a Mobile Platform
Arrhythmia means abnormal rate of heart contraction which is dangerous as it may also cause death. The work proposed in this paper mainly deals with the development of an efficient arrhythmia detection algorithm using ECG signal so that detection of arrhythmia at initial stages is possible using a smart-phone which is readily available anywhere which makes complete system mobile. Subjects for e...
متن کاملReconstruction Methods for Level-Crossing Sampling
Level-crossing sampling refers to a sampling method that generates a sequence of timing samples when a signal crosses a specified set of levels. Conventional sampling techniques more typically rely on producing a sequence of amplitude samples at a specified set of timings. Level-crossing sampling has been considered as a promising alternative to time sampling when it is difficult to implement h...
