Power supply and signal filtering for 24-hour ECG

The goal of this research is to present signals filtering for the high resolution Hotter monitoring system. The first part of this paper concentrates on working of human heart and description of architecture of biopotentials recorder. This part also includes proper amplification and filtration of interferences of bioelectric signals. The second part of this research presents practical realization of Holter monitoring system. Special attention is put on proper selection of components of the recorder and joining them into optimal structure.
