Abstract:
The present work generalises the subtraction procedure, which removes the power-line interference without affecting the components intrinsic to the ECG. It is based on previous investigations, dealing separately with the cases of odd and even multiplicity/non-multiplicity between the sampling rate and the power-line frequency. The study proposes an integration of both cases, using common equations and algorithm. The theoretical conclusions are implemented in a program written in MATLAB environment. The algorithm and the program are tested by many particular cases and the introduced errors are evaluated. The work represents a suitable platform for accurate investigation, analysis and development of the subtraction procedure.
