The principle of discrete wavelet transform is used to estimate the signal spectrum. A method of feature extraction based on discrete wavelet transform is proposed. The feature extraction of measured data is carried out to obtain a stable and efficient line spectrum and continuous spectrum, which improves the line spectrum and continuous Spectral separation accuracy
