The ECG signal contain base line wander noise(0.5 to 0.6Hz), breathing noise (5Hz), power line interference(50Hz) and EMG noise(above 100Hz).Electrode Motion artifact noise can be reduced by minimizing movement made by the patient. High pass filter can be used to remove base line wander noise with cutoff frequency of 0.6 Hz. High pass filter can be used to remove breathing noise with cutoff frequency of 6 Hz.50 Hz power line interference can be removed using band stop filter. QRS detection is done using differentiation method. Scilab. is used for performing signal processing task of removing common noise in ECG signal. SNR of Input signals with base line wander noise, breathing and PLI noise when passed to FIR(high pass and band stop filter order 51) shows improvement in output SNR.
