[A new method for lowering noise of ECG signal]

In this article, a new method is introduced to reduce the noise in ECG signal. We use accumulation-division method in frequency area, which can solve the problem of locating the initial position. This problem exists definitely in time area. By using this method, automation in disposing the noise can be realized. The result of this disposing is an integrated and low noise level cycle of ECG signal, which contains all useful characteristic signals. We hope it will be convenient for doctors.
