Analysis of Digital Signals using Wavelet Packet Tree

Wavelet packet tree analyses both low and high frequency sub-bands of a signal, consequently provides more elaborate information to be exploited for extracting features. WPT provides us with a valuable information which can be used to form a feature vector for any type of digital signals, in this paper we will provide an analysis of WPT to use the approximations and details for various levels of WPT to get the needed information necessary to create digital signal features vector.
