Discrete Wavelet Transform using Daubechies Wavelet family for Stationery and non-stationery signal and test with ECG signal for compression as well. The Matlab code are very simple and detailed one to understand easily. Can change code and produce on for ones project as well.
These code provided with outputs to understand what exactly we are doing and get known what DWT exactly is. I tried my best to provide simple code.
