摘要：

basic concepts of the discrete wavelet transform (DWT) and the wavelet packet transform (WPT) are presented and illustrated. WPT is then applied to real and simulated signals. Different approaches to the WPT coefficients selection aiming at signal compression and denoising are described. Uniform compression of the set of signals is discussed as well.
