Reconstructs a signal from the Gaussian chirplet elementary functions. Wire data to the signal input to determine the polymorphic instance to use or manually select the instance.

Use the pull-down menu to select an instance of this VI.

Inputs/Outputs

  • cnclst.png sampling info

    sampling info specifies the sampling information of the reconstructed signal.

  • cdbl.png sampling rate

    sampling rate specifies the sampling rate of the reconstructed signal in hertz. sampling rate must be greater than 0, or this VI sets sampling rate to 1 automatically.

  • ci32.png length

    length specifies the length, in samples, of the reconstructed signal. The default is -1, which specifies that length equals the largest value of center + 4xstandard deviation.

  • c1dnclst.png chirplet info

    chirplet info specifies the parameters of each elementary function.

  • ccdb.png amplitude

    amplitude specifies the complex amplitude of the chirplet or Gaussian pulse.

  • cdbl.png standard deviation

    standard deviation specifies the standard deviation of the Gaussian envelope in seconds.

  • cdbl.png center

    center specifies the central time of the Gaussian envelope in seconds.

  • cdbl.png frequency

    frequency specifies the central frequency of the chirplet in hertz.

  • cdbl.png chirp rate

    chirp rate specifies the sweep rate of the carrier sine wave in hertz per second.

  • cerrcodeclst.png error in (no error)

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

  • i1ddbl.png signal

    signal returns the reconstructed signal.

  • ierrcodeclst.png error out

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