= Wavelet packet decomposition
{wiki=Wavelet_packet_decomposition}
Wavelet packet decomposition is a technique used in signal processing and data analysis that extends the principles of traditional wavelet decomposition. Here’s a breakdown of the concept: \#\#\# Basics of Wavelet Decomposition 1. **Wavelets**: A wavelet is a mathematical function that can be used to represent signals at different scales or resolutions. Unlike traditional Fourier transform methods, wavelets can localize signals both in time (or space) and frequency.
