Heart problems are increasing day by day and Electrocardiogram (ECG) is a vital signal monitoring measurement of the cardiac activity. One of the main problems in biomedical signals like electrocardiogram is the separation of the desired signal from noises caused by power line interference, muscle artifacts, baseline wandering and electrode artifacts. Different types of digital filters are used to separate signal components from unwanted frequency ranges. Present paper deals with design and simulation of digital techniques like FIR filter, IIR filter and Kaiser Window which demonstrates the removal of power line interference (PLI) noise. Complete design is performed with the help of FDA tool in the Mat lab. The result shows before filtering and after filtering results which clearly indicates the removal of the power line interference in the ECG signal.
