Abstract

The project intends to specify and to develop a system of capturing and processing biomedical signals based on modular hardware and totally configurable software that offers both high performance and a high degree of flexibility. This system will be based on modules of simple and standardized hardware and from groupings of which a high processing capacity in numbers of channels and a high degree of sampling can be obtained. Particular emphasis will be given to the configurability of this system, allowing for its use across a wide range of applications, as well as its easy adaptation to other types of application, even outside of the biological area. Consequently, the short term goal is: to specify the design of the distributed system of capturing and processing (biological) signals capable of processing up to 64 channels, with a sample frequency of 20 kHz per channel with presentation and digital filtration of the signal in real time under the control of a microcomputer, and to define a high performance communication protocol between the microcomputer and the acquisition modules and the digital processing of signals, and to formulate processing algorithms in real time for application in neurophysiology. In the long term, the intention is to consolidate technological training within the project as well as the implementation of capturing and digital processing systems of high performance signals.
