Fourier Spectral Analysis

Basic, Professional, Developer Suite

Provides three different spectral procedures.

Fourier Spectrum for Unevenly Sampled Data

Spectral Analysis Option

Generates a Lomb-Scargle periodogram for data sets with unevenly spaced X values and for data containing void values.

Harmonic Estimation

Spectral Analysis Option

Generates a parametric model of the signal.

Instantaneous Quantity

Spectral Analysis Option

Calculates different instantaneous quantities (instantaneous amplitude, instantaneous phase as well as instantaneous frequency) using the Hilbert transform.

Harmonic Filter

Order Tracking Option

Removes or extracts harmonic components of a selected order from time signals.

Order Filter

Order Tracking Option

Calculates order tracking for speed-dependent oscillations by bandpass filtering individual orders in the revolution domain.

Spectral Estimators

Spectral Analysis Option

Provides three spectral estimators with high frequency resolution.

Shock Response Spectrum

Spectral Analysis Option

Calculates the shock response spectrum from the responses of several SDOF systems that are excited by an accelerometer signal.

Revolution Synchronous Order Tracking

Order Tracking Option

Calculates an order tracking analysis for speed-dependent oscillations by Fourier analysis of the signal converted in the revolution domain.

Time-Frequency Spectral Analysis

Professional, Developer Suite

Provides two different time-frequency spectral procedures for non-stationary data.
