An Improved Self-Adaptive Filter Based on LMS Algorithm for Filtering 50Hz Interference in ECG Signals

摘要：

In this paper, we firstly introduce three conventional digital filtering methods and analyze their qualities of filtering. Then we use a new method based on self-adaptive digital filter and median filter for their defects, and simulate it. It is demonstrated that not only the noises are successfully restrained, but also the useful information is preserved as much as possible, and the performance of the new method is superior to the others.
