Abstract :
We propose the use of a lattice based second order infinite impulse response (IIR) notch filter with a simplified adaptation algorithm for removal of the power line frequency from ECG signals. The performance of this filter is better as compared to a second order infinite impulse response (IIR) notch filter for real time ECG recording systems where the frequency of the line varies over a narrow range about 50 Hz.
