Figure 4.

Simulation data from eight trials with the differentiator network are shown. Different values of C_m,1 and C_m,2 were used in each. ${\mathit{U}}_{\mathit{post}}^{\ast }$ is plotted in blue, U₂ − U₁ is plotted in dotted red, and the actual rate of change of the input, d/dt(I_app), is plotted in gold.
