Inputs/Outputs

  • ccclst.png cepstrum —

    cepstrum specifies information about the cepstrum.

  • cdbl.png t0 —

    t0 specifies the lower boundary of the time range.

  • cdbl.png dt —

    dt specifies the time increment.

  • c1ddbl.png C(t) —

    C(t) specifies the complex cepstrum.

  • cnclst.png phase info —

    phase info specifies the phase information of the original time series. You can obtain this information when estimating the complex cepstrum.

  • cdbl.png DC —

    DC specifies the phase information at zero frequency.

  • cdbl.png Nyquist —

    Nyquist specifies the phase information at the Nyquist frequency.

  • 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 Xt —

    Xt returns a univariate time series reconstructed with the information from cepstrum and phase info.

  • ierrcodeclst.png error out —

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