Abstract

This project is titled real-time ECG acquisition system. An ECG is a test that records the activity of the heart over time. Each portion of the ECG waveform can hint whether the patient is in good health or else. ECG signal are usually very small (approximately ImV) and therefore prone to interferences (in the form of noise which commonly produced the 50Hz power supply and by changing of skin electrode contact resistor). This project will focus on designing a system that will amplify and filter the ECG signals from six different sources and display them. To measure the ECG signal, an amplifier and a driven right leg circuit are used to reduce the 50Hz common noise. Then, it will go thorough the filter circuits where LPF will eliminate high frequency noise components and HPF will remove the base line drift. The system is consists of instrumentation amplifier IC AD620, precision amplifier OP97 and operational amplifier LM74 1.
