Computer filtering of an ECG signal based on the prior knowledge principle-general concept

Abstract

A new computer method for ECG signal filtering is discussed. This method is based on a concept which is called "The Prior Knowledge Principle" (PKP). The PKP assumes that the measured signal contains the ECG signal itself and environmental noises. An artificial signal with amplitude and time resembling the real ECG one has been constructed. The cases of white and network noises are analyzed, with the level of noise changed from 0 to 100%. The error of the methods has been calculated and it has been found that it does not rise above 20%. INTRODUCTIO NThe uroblem of ECG filtering is widely discussed rl -51.
