摘要
小波分析是傅立叶分析的重大突破。本文运用小波变换多尺度分析的思想,探讨了用DB小波进行信号去噪的计算方法。结果表明。
Watvelet analysis is a magnitude breakthrough of Fourier analysis. This paper discusses the computing method removing noise from a blasting seismic signal with DB wavelet. The result indicates that it is significant to de-noise the blasting seismic signals with wavelet transform.
