Abstract:
Wavelet transform(WT) is a powerful technique in signal separation and can improve the signal-to-noise ratio by separating the white noise and useful signal.The method in the paper introduces the concepts of Wavelet transform.According to the analysis of Wavelet coefficients between the noise and signal at different levels,the appropriate filter is realized.The patch clamp experiment results demonstrate the feasibility of the method.
