Electrocardiogram (ECG) is used for detection and diagnosis of various heart related diseases. ECG signal plays a vital role in monitoring the heart functions of the patients. There are several noises present in the ECG signal like muscle noise, PLI (Power line interference), contact noise etc. Most commonly the digital FIR filters are designed to reduce the noise. This paper deals with mixed windowing technique for designing a Digital FIR low pass filter. Mixed windowing technique is nothing but the combination of any two windowing techniques. The performance of the filter outputs based upon the SNR. Finally, the SNR of various mixed windowing techniques are compared with the SNR of individual windowing techniques .The whole work will be done in MATLAB Environment.
