Angle-Frequency analysis is interesting when working on reciprocating machine. It allows to identify specific events. | Angle-Frequency analysis is interesting when working on reciprocating machine. It allows to identify specific events. | ||
The method implemented in the software is based on the Wigner-Ville algorithm. | The method implemented in the software is based on the [https://en.wikipedia.org/wiki/Wigner_distribution_function Wigner-Ville algorithm]. | ||
This method is particularly adapted for short transient signal where the STFT is not sufficient. Another advantage is the good resolution both in angle and frequency one can obtain. | This method is particularly adapted for short transient signal where the STFT is not sufficient.
