When

ω RC

is of order one, the output consists of visibly curved exponential charging and discharging arcs, with neither long flat plateaus nor nearly straight sides. At

ω RC = 1

M = V_{0} tanh (π /2) ≃ 0.9172 V_{0} .

(1)

The output is continuous and lags the abrupt input transitions; its precise shape is the periodic solution given in the parent part.
