Gravitational-wave signal analysis based on Synchroextracting Transform (SET)

Gravitational-wave signal analysis, Time-frequency analysis, Synchroextracting Transform.

We investigate the applicability of the proposed SET method to analyze a gravitational-wave (GW) signal generated in the procedure of inspiral and merger of a pair of black holes. GW signal detection just won the 2017 Nobel Prize, and GW signal analysis is a very challenging task. The SET is a high-resolution time-frequency (TF) analysis tool, that allows for signal reconstruction. Therefore, the high-resolution TF representation of GW signal can be obtained by the SET, that is shown in the Figure.
