A Canonical Model of Multistability and Scale-Invariance in Biological Systems
Figure 4
Bistability with purely additive noise for three different values of the bifurcation parameter β.
A: Bifurcation diagram for λ = 4. The three values of β used here are indicated in red, blue and green. B: Time course of uncorrelated noise input . C: Phase portraits of example integrations. Black/red indicates inward/outward flow. D: Time series of example integrations. E: Corresponding power PDFs.
is the discrete-time analytic signal of r (i.e. the amplitude envelope of r).
