摘要：
Some advantages of the discrete time algorithm of wavelet decomposition are analysed and some of its problems, such as the discrete convolution operation formula of wavelet coefficients and the wavelet components, the sampling principle and technology to wavelet, the scale range, the characteristic and solving method of the end effect, are discussed. The cost and precision of the algorithm are also analyzed. Using the advanced virtual instrument technology, a virtual signal analyzer is developed for the wavelet transform based on the discrete time algorithm. Finally, some examples are given for the application of the discrete time algorithm of the wavelet decomposition with our analyzer.
