An ECG signal is usually corrupted by various types of noises. Some of these noises are power line interface, baseline drift, muscle contraction, motion artifacts, electrosurgical noise, instrumentation noise and electromyography noises. It is highly required to develop a method which can filter ECG signal noises significantly. In this work, an EMD along with adaptive switching mean filter based new method for de-noising of ECG signal has been proposed. Unlike, conventional EMD based de-noising approaches, where only lower orders IMFs are denoised in this work, along with EMD, ASMF operation has been employed for further signal quality improvement. The lower order IMFs are filtered through wavelet de-noising technique to reduce high-frequency artifacts and retain the QRS complexes. Then, considering the effectiveness of ASMF, for further enhancement of signal quality adaptive switching mean filtering is performed. The validity of the performance of the described technique is evaluated on standard MIT-BIH arrhythmia database. Gaussian noise at different signal to noise ratio (SNR) levels are added to the original signals
