Fourier analysis calculates the spectral components, in modulus and phase, of the specified signals. The results of the Fourier analysis are calculated based on the currently set vector as a scale that usually corresponds to the time vector generated as a result of a transient analysis. The vectors whose spectral components are to be calculated are interpolated on a corresponding scale to a period of the fundamental frequency. The interpolation function is regulated by the options: Polynomial degree for interpolation function and Number of interpolated points for Fourier analysis.

SuggerimentoTip:

The options can be set in the tab Vectors in the Application properties dialog box. The dialog can be activated by selecting the Settings » Application Properties command or via the key combination CTRL+ALT+A.
