Development of Sound Card Based Dual Channel Novel Bio-signal Simulator

摘要

To subside the risk factors as well as the requirements for various age groups of human beings, bio-signal simulators are developed since they exactly mimic the real biological signals. While existing simulators are generating only one bio-signal, this work demonstrates the dual channel simulator capable of producing two bio-signals simultaneously. This task specializes with the simulation of Electrocardiogram (ECG) and Arterial Blood Pressure (ABP) signals from Physionet, the standard database used to generate signals. The sampling frequency for the ECG and ABP signals are 100Hz and 125Hz respectively. These signals are processed and transmitted through the sound card audio output port of the personal computer and can be used for testing and calibrating the medical instruments, research and development and experimental activities in educational institutions.
