In the time-domain: (tau1 * nengolib.Lowpass(tau1) - tau2 * nengolib.Lowpass(tau2)) / (tau1 - tau2) In the frequency-domain: 1 / (tau1 * s + 1) / (tau2 * s + 1)

Include derivation that these two definitions are equivalent (with the latter being well-defined when tau1 == tau2).

Derivation is alluded to in test comments.
