This yielded the following plot: Now, when I used the waverec method, the signal reconstruction was quite accurate. The source code of this file is hosted on GitHub.

My first step was to see how I could reconstruct a given input signal using the wavelet coefficients. The function wavedec performs a tree decomposition, which means a filtering followed by a downsampling of a factor 2 for a dyadic scheme.

Is there a function for a multilevel one-dimensional wavelet analysis using a specific wavelet? How do we handle problem users?


Because Daubechies’ wavelets are orthogonal, they lead to a perfect reconstruction and this way you can get your original signal back after reconstruction.
