Abstract: Least Square Weighted Smoothing Filter (LSW-SF) method is used to filter Magnetic Resonance Sound (MRS) signals, which is compared with the moving average filter method. Results of a large number of simulation experiments show the following characteristics. First, the more accurate characteristic parameters of MRS can be obtained using the LSW-SF method, and the Signal to Noise Ratio (SNR) is also improved. Second, the LSW-SF method is more suitable for random noise and rush noise removal. Third, appropriate weights should be chosen when the LSW-SF method is used to wipe out noise. Among them fitting error of MRS signal characteristic parameters can be controlled within 1%, and the smoothness of the signal curve is greatly improved. Meanwhile, the filter processing of the measured data indicates this method is effective.

Key words: electrical engineering, magnetic resonance sounding (MRS), data filtering, moving average, least squares
