The graph of extremum values of Y in function of σ for a simple activation process. The extremum values of Y in function of σ for a simple activation process (Fig 1. (a)) are plotted thanks to the equations (2) of the main text. Y _max is the maximum reached by the protein, <Y > _T is the mean concentration of the protein averaged over one period T, Y _min is the minimal value reached by the protein, $\kappa =\frac{\beta }{\alpha }$ (dotted line) represents the stationary state that the protein would attain if the stimulation was constant and Y _L (dashed line) is the asymptotic value reached by Y _max when the inter-pulse interval σ becomes very large. The parameters are: α = 0.01 min^-1, β = 10 nM.min^-1, τ = 100 min.
