Abstract: A novel power line interference removal method based on blind signal separation algorithm was proposed. The regular methods for power line interference removal were notch filter method and adaptive filter method. Part of the frequency component in desired signal would lose if there was same frequency component between power line interference signal and desired signal. The desired signal and the power line interference signal was commonly coming from different source. The power line interference removal problem was transformed into blind signal separation problem by constructing observation signal artificially. The blind separation algorithm based on unifying model was used for solving the transformed blind separation problem and the desired signal without power line interference could be got. The simulation results on electrocardiogram signal show that the power line interference can be removed efficiently using the method proposed and the signal recovery precise is high.

Abstract: With the change of the human life style, heart disease has become one of the main diseases threatening human life and health. Promptly, accurately and completely achieving electrocardiogram (ECG) signal has vital significance for discovering and treating heart disease as soon as possible. However, the traditional professional electrocardiograph has complex structure, high price, and it is not suitable to carry on the popularization application. Therefore, this article proposes a new type of ECG signal sample and analysis system based on a personal computer, which realizes acquisition and analysis function through the LabVIEW programming. The research result shows that it has not only perfect function, convenient operation, easy to use, but also low price, and it is very suitable to universal application. So, it has very good practical value.
