Pulse-Width-Modulation with Zero Phase Error Tracking Controller System for Electrocardiogram Feature Extraction and Tracking from Virtual Patient

摘要

A patient's Electrocardiogram (ECG) monitoring is a relatively considered for long time period during the testing process. Additionally, specific application has been essential for acquiring the high resolution ECG. So, generating an artificial ECG signal from virtual patient and it has applicability in different kind of areas such as low voltage singles are needed and time skewed and so on. The waveform signal for each and every channel can be changed effortlessly to match the need of various kinds of application. This kind of application has many advantages such as simplified the utilization of the ECG signals without required for non-invasive and invasive approaches and reducing the test time. Thus, in this paper presents analog-to-digital converter such as a Pulse-Width-Modulation (PWM) for electrocardiogram (ECG) feature extraction process. To track and generate an artificial ECG signal by using extracted features from PWM which is done by using Zero Phase Error Tracking Controller (ZPETC) tracking process. The generated signals are seen as real ECG signals taken from the heart activities, which processes are done by using microcontroller. This proposed system can be utilized in the testing of multi-inputs ECG structure without using a human or added testing cost. This approach generates to enhance the accuracy of the signal waveform without improving the hardware complexity or computational complexity.
