Abstract: A Gocrtzcl based all digital phase locked loop for removing power line interference from the ECG signal is proposed. A power line interference is artificially iiitroduccd in ECG signal and this proposed scheme tracks the amplitude and phase of all the interference components for power line frequency deviations from input signal frequency (i.e. 50 Hz). The output sampling frequency is adjusted with the help of all digital phase locked loop (ADPLL) to correct the phase errors introduced by the SG filter whenever variations in frequency occur. Main building blocks of proposed method are discussed. MATLAB simulation results are discussed and future work is to make this scheme adaptive for large variation in input frequency.
