In this paper the spectral and the transforming properties of Shannon orthogonal wavelet are analyzed.The algorithm of Shannon orthogonal wavelet transform and reverse transform is realized by using fast Fourier transform.The result of the experiment shows that Shannon orthogonal wavelet plays an important part not only in connecting wavelet transform and Fourier transform,but also in the application of wavelet transform to real time signal processing.
