摘要: Wavelets has become a very popular matter of investigations, due to their great potential applications. With respect the classic windowed Fourier analysis, whose basis functions have same width, wavelet bases time-widths adapted frequency. Therefore transform is better able zoom-in on short-lived high frequency phenomena.
