Özet:

This paper presents the first real and well tested prototyping duty cycle modulation (DCM) signal transmission system. The experimented system is applied to the transmission of ECG signals. It consists of an ECG signal acquisition system, a duty cycle modulation transmitter, a coaxial cable transmission medium and finally a simple low-pass filter as receiver. After a brief review of the literature highlighting the interest of this experiment, we analytically developed different parts of the proposed system. The experimental workbench and main results obtained are presented. These yield very good results since in addition to the high quality of ECG signal reconstitution, we manage to eliminate the power line interference induced during transmission. These results experimentally confirm the feasibility as well as new perspectives of using the proposed systems as a simple remote biomedical instrument. Cite as: Nguefack LT, Paune F, Mbihi J.
