Reconstructs the wavelet packet (WP) coefficients of the node that path specifies. The node that path specifies must not be a terminal node of the wavelet packet tree.

Inputs/Outputs

  • ccclst.png WP session —

    WP session specifies a reference to an existing wavelet packet structure.

  • cu64.png ref —

  • catrn.png t0 —

  • cdbl.png dt —

  • cstr.png path —

    path specifies the path associated with a node of the wavelet packet tree. For this VI, path must refer to a node with children. path is a combination of the characters 0 and 1, where 0 represents lowpass filtering, and 1 represents highpass filtering.

    For example, a value of 101 indicates that this VI passes the signal through a highpass filter, through a lowpass filter, and then through a highpass filter. path can be root, which represents the original signal without any filtering operation.

  • cerrcodeclst.png error in (no error) —

    error in describes error conditions that occur before this node runs. This input provides standard error in functionality.

  • icclst.png WP session out —

    WP session out returns a reference to an existing wavelet packet structure, which this VI can modify.

  • iu64.png ref —

  • iatrn.png t0 —

  • idbl.png dt —

  • ierrcodeclst.png error out —

    error out contains error information. This output provides standard error out functionality.
