Currently, denoising techniques for ECG signals are mostly available in the wavelet transform domain. In this paper, an approach for denoising the ECG signals in the Framelet domain is proposed. Initially, signals are decomposed using the Framelet transform. After decomposition, they are denoised using a median based thresholding method. The performance evaluation is carried out by comparing the results with that of the wavelet transform.
