Abstract :
The device is designed for the identification of slow changing random signals with the spectrum frequency lower than 30Hz. It is especially suitable for recognizing, identifying and analyzing the wave components of electrocardiograms. The device has two channels for a simultaneous input of analogous signals. A high input resistance allows the amplification of biosignals, with low voltage and power. The device secures the filtration of disturbances higher than 30Hz reducing them to 80dB. The speed of microcomputer is 12mgHz, and the memory is 128kByte. The device is supplied with a liquid-crystal graphic display with 128x64 points of G-1216 type. It is portable: it has an inner power (battery) supply. Its weight is less than 300gr, and the size is 170x90x35.
