18.12.3 Reconstruction

Reconstruction

In wavelet reconstruction, a signal can be reconstructed from its approximation coefficients (ca) and detail coefficients (cd) with this function. The coefficients are first upsampled and then filtered. The filters are determined by the chosen wavelet, and should correspond to the wavelet used in the decomposition that has produced the coefficients. Otherwise, the signal cannot be reconstructed correctly.

To Use Wavelet Reconstruction Tool

1. Make a workbook or a graph active.
2. Select Analysis: Signal Processing: Wavelet: Reconstruction from the Origin menu.
