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.
