Abstract：In order to remove the noise from the discharging signal of dorsal root ganglion(DRG)neurons for further analysis,the wavelet filtering method was used.First the signal with noise was decomposed through the harr wavelet,and then the GCV algorithm was used to determine?the optimal threshold based on soft-threshold method,at last the signal was reconstructed.It demonstrates that the method using GCV algorithm can effectively remove the noise from neurons discharging signal.The denoised waveform is smooth and continuous,and the signal peaks related details are retained.
