A SIMPLE BIOELECRICAL SIGNAL SIMULATOR FOR MEASUREMENT DEVICE TESTING

Antti Vehkaoja, Jukka Lekkala

Abstract

A very simple PC based system for simulation of bioelectrical signals is presented. In addition to a regular PC with an audio card and the constructed software only few passive components are needed to accurately mimic the waveforms of the original recorded bioelectrical signals stored in the PC's hard drive. Alternatively, the simulated signals that are generated from the original recordings by Matlab can be played back with an mp3-player. Due to the nature of our method and the bandwidth limitations of PCs' audio card, the system is not suitable for simulation of high frequency signals but for bioelectrical signals like electrocardiogram (EKG) the method suits very well.
