Table 1 Frequency modulated (FM) classes: linear FM (LFM), sinusoidal FM (SFM), piecewise linear FM (PWLFM), and hyperbolic FM (HFM)
From: Instantaneous frequency based newborn EEG seizure characterisation
Name | IF law, f(t) | Parameter set, Ψ |
|---|---|---|
LFM | f0 + f r t | [f0, f r ] |
SFM |
| [f c , m, f m , θ] |
PWLFM | (α1 − α)|t − B1| + (α − α2)|t − B2| | [α, α1, α2, B1, B2, f m ] |
+ α1(t − B1) + α2(t − B2) + f m | ||
HFM | f0 / (1 + f r t) | [f0, f r ] |
