The dependence of errors of reconstruction Δ_Z and Δ_ψ, Eqs (10) and (12), on correlation time τ of the driving for the Morris-Lecar oscillator, Eq. (7). In (a,b) for each value of τ, 100 points corresponding to different realizations of noise are plotted with blue dots and their average in colors: Δ_Z in green, Δ_ψ in red (and ${\mathrm{\Delta }}_{{\psi }_T}$ in orange for reference). Shown in (c–h) are segments of signal on two time scales for three values of correlation time τ. In orange the voltage V(t) (only in (c–e)) and in blue the input signal p(t), scaled for being visually comparable. The times of zero phase t_m are marked with vertical black lines. The driving strength is $\epsilon \parallel Z\parallel =3$.
