COST EFFECTIVE FLEXIBLE MODULAR SYSTEM FOR ACQUISITION AND PROCESSING OF BIOLOGICAL SIGNALS BASED ON ADVANCED SIGNAL PROCESSING

摘要

Measurement of signals from biological objects usually requires complex and expensive system. This paper presents a simple, cost effective, computer controlled modular systems consisting of self developed modules and modules from a few vendors and own software developed in Lab VIEW. The system enables multichannel data acquisition with sampling frequency a few kHz with nearly unlimited lengths, triggering and pretriggering records. The records are stored in signal database and processed by software in PC using various advanced digital signal processing methods for recovering distorted signal. The system was developed and has been used for biological experiments on rats focused on evoked potentials.
