Level 1, 2, and 3 Wavelet Decomposition

This program enables you to perform level 1, 2, and 3 wavelet decomposition and display the corresponding decomposition results. The implementation typically utilizes wavelet transform functions (such as wavedec in MATLAB) to recursively decompose signals into approximation and detail coefficients. Through this functionality, you can gain deeper insights into different decomposition levels and observe the visualization of results at each stage, which helps in better understanding and analyzing data characteristics. Additionally, the program provides supplementary features including data processing tools and visualization analysis utilities to help you comprehensively master and apply wavelet decomposition techniques. The code structure likely includes parameter configuration for wavelet type selection (e.g., Daubechies wavelets), decomposition level control, and graphical output generation for coefficient visualization. Whether for academic research or engineering applications, this program offers enhanced possibilities and flexibility for multiscale signal analysis.
