Understanding dynamics of the system using Hilbert phases: An application to study neonatal and fetal brain signals
The Hilbert phase φ(t) of a signal x(t) exhibits slips when the magnitude of their successive phase difference |φ(t(i)(+1)) − φ(t(i))| exceeds π. By applying this approach to periodic, uncorrelated, and long-range correlated data, we show that the standard deviation of the time difference between th...
