    Which one is right about wavelet transforms? A: Wavelet transforms store large fractions of the strongest of the wavelet coefficients. B: Wavelet transforms are completely different from discrete Fourier transform (DFT). C: Each transform has 2 functions: smoothing, difference. D: Wavelet transforms means applying to pairs of data, resulting in two set of data of length L.

    Which one is right about wavelet transforms? A: Wavelet transforms store large fractions of the strongest of the wavelet coefficients. B: The DWT decomposes each segment of time series via the successive use of low-pass and high-pass filtering at appropriate levels. C: Wavelet transforms can be used for reducing data and smoothing data. D: Wavelet transforms means applying to pairs of data, resulting in two set of data of the same length.
