Abstract: The present invention discloses a method for the removal of power line interference (PLI) to the signal parts of which are abrupt. First, to the non-abrupt part of the original input signal, we pass it to the notch filter, and get the output as the system output. Then, to the abrupt part, we subtract previous output from the original input signal; and add a straight line, connecting the starting and end of previous output, to the result of the subtraction to get the input of the notch filter. After processing of the notch filter, we add previous output to current output of the notch filter; and subtract the straight line as before from the sum to get the output of this step. We repeat this processing several times. During the detection of electrocardiogram (ECG), 50/60 Hz power line interference conceals the subtle changes in the original ECG, which affects the diagnosis.
