A Hybrid De-noising Method Based on Wavelet and Median Filter for Aero-engines Gas Path Electrostatic Monitoring

摘要：

In this paper, we present a hybrid denoising method to remove the noise of electrostatic monitoring signal. Firstly, we introduce the method which combines the advantage of the median filter and the wavelet multilevel threshold de-noise based on the Birge-Massart strategy, then present one methodology to compute the signal-to-noise by wavelet decomposing, and take the improved signal-to-noise as the evaluation index to compare the de-noise methods. The two illustrative examples are employed to validate the effectiveness of the hybrid method proposed in the paper.
