Design And Implementation of a Biomedical Signals Generator Based on Microcontroller

Abstract

Biomedical signals are one of the most important parameters in the diagnosis, so the doctors and clinical trainers must be familiar with these signals. Biomedical signals generator is an electronic device used to simulate such signals for the above-mentioned purpose. The biomedical signals generator (BIO-SG) is a useful tool for biomedical signals devices for calibration, monitoring, and incorporation in educational tasks and clinical environments. a biomedical signals generator based on a microcontroller and also we use a digital to analog converter and an amplifier to act as a conditioning circuit for the signal and made it easy to show on an oscilloscope. The device is based on a microcontroller to generate the basic ECG wave and EMG wave, these signals can be used as an input to the ECG and EMG machines. the results show that the generated waves with low error rate compared with the biomedical standard waves.
