TSA Inverse Complex Cepstrum (Waveform)

cepstrum specifies information about the cepstrum.
t0 specifies the lower boundary of the time range.
dt specifies the time increment.
C(t) specifies the complex cepstrum.
phase info specifies the phase information of the original time series. You can obtain this information when estimating the complex cepstrum.
DC specifies the phase information at zero frequency.
Nyquist specifies the phase information at the Nyquist frequency.
error in describes error conditions that occur before this node runs. This input provides standard error in functionality.
Xt returns a univariate time series reconstructed with the information from cepstrum and phase info.
error out contains error information. This output provides standard error out functionality.

TSA Inverse Complex Cepstrum (Array)

cepstrum specifies information about the cepstrum.
