A system and a method for recording bioelectric signals relate to medical technology, in particular to devices for recording bioelectric signals for the determination of human cardiovascular system parameters by noninvasive methods, including domestic use. The system and method are based on use of digital sensor platform which operation is based on primary digital conversion on the principle of bioelectric signal energy accumulation. In the system realizing the method for recording bioelectric signals the sensor platform performs most of the system functions, in particular primary conversion of bioelectric signal, its transformation to digital code, digital processing of signals, calculation of basic cardiovascular system parameters. The transformation to digital code is performed simultaneously with primary conversion without preliminary amplification and other analog operations with signal due to matching all signals in the sensor, this makes it possible to redistribute functions in the system according to sensor system concept. |
