Transmitting a biomedical signal in a TV White Spaces Network

Abstract

In an effort to examine the heart condition, electrodes of Electrocardiogram (ECG) machine are placed on the skin of the patient thereby detecting depolarization and repolarisation of the myocardium which is the muscular tissue of the heart. The readings are therefore displayed on an electrocardiograph. It is therefore important to note that there is a technical limitation in obtaining readings in the sense that upon movement of the patient, the equipment equally moves hence artefact making interpretation difficult. This paper is therefore trying to eliminate the stated technical problem by designing a low cost solution incorporating an instrumentation amplifier with high common mode rejection ratio (CMRR) and the biomedical signal is transmitted from the patient in a remote hospital to the heart specialist for analysis using TV White Spaces network.
