Owning Palette: Correlation and Spectral Analysis VIs

Requires: Advanced Signal Processing Toolkit. This topic might not match its corresponding palette in LabVIEW depending on your operating system, licensed product(s), and target.

Use the Advanced PSD VIs to perform advanced analysis methods on the estimated power spectral density (PSD), such as averaging and liftering. The word lifter is an anagram of the word filter.

The VIs on this palette can return general LabVIEW error codes or specific Time Series Analysis error codes.

Palette ObjectDescription
TSA Average PSDContinuously averages the estimated power spectral density (PSD) of a univariate time series with different averaging methods.
TSA Lifter PSDSeparates the harmonic peaks in the power spectral density (PSD) by computing the power cepstrum of the input PSD and filtering out unnecessary harmonic peaks in the power cepstrum. The word lifter is an anagram of the word filter.
