The development of biosignal processing system (BPS-SWU V1.0) for learning and research in biomedical engineering

摘要

This paper presents a preliminary study on the development and the experiment of biosignal processing system (BPS-SWU v1.0) for learning and research application for undergraduate students in biomedical signal processing laboratory (BME LAB). The first version of our system, the frequency range of lung sound in the normal subjects was investigated by using spectral analysis technique. The experimental results indicate the characteristics of lung sound frequency in the form of spectrogram. The results show a frequency range of the lung sound in normal subjects from 34.65-119.40 Hz with certain frequency characteristics. The results are very promising.
