In this paper, calculations of threshold using genetic algorithm (GA) is studied. From the results, it can be found that the threshold value calculated using GA is such that the actual PRD (Percent root mean square difference) after threshold is almost equal to the UPRD (User specified PRD). First ECG signal is transformed using wavelet transform (WT) and discrete cosine transform (DCT). The transformed coefficients (TC) are then thresholded by genetic algorithm. The thresholding is done in a way so that error between actual PRD and UPRD remains within the specified limits.
