Fisiógrafo digital: sistema de aquisição e processamento de sinais fisiológicos em IBM-PC.

Abstract

This dissertation presents various aspects of a system for the acquisition and processing of physiological signals, the "Fisiografo Digital". This apparatus has a modular structure and consists of a microcomputer, signal conditioning modules and the control program. The control program commands the acquisition, storage, processing and visualisation of the physiological signals. Different techniques for the acquisition and storage of these signals with an IBM-PC compatible microcomputer are described. The software has been written in the modular form to enable quick and relatively easy modifications. The user interface is friendly and the commands are issued by Pop-up type menus.
