Application of wavelet transform in MATLAB in ECG signal denoising
1. Introduction The ECG (electrocardiogram) signal is a very valuable biological signal that describes the function of the heart by recording its electrical activity. However, in the actual data collection process, ECG signals are often interfered by various noises, such as electromyographic noise, baseline drift, and electrical network interference. In order to analyze and diagnose […]
