Instantaneous phase and magnitude with the Hilbert transform
Nettet23. mai 2024 · I am trying to obtain the phase difference between two non-stationary signals. I have tried using both Hilbert transform and Complex Wavelet Transform. … NettetWe explore possible interpretation of those findings in the context of the cinematic view of cognition, in particular cortical phase transitions. In addition to traditional Fourier-based correlational analysis of cortical signals, we introduce Hilbert analysis, which allows to monitor rapid phase synchronization-desynchronization transitions. fbi move to maryland
