This tutorial covers realization of a continuous-time second-order lowpass filter as a state-space model which is then digitized via both forward and backward Euler schemes to produce the so-called Chamberlin form of a digital resonator (which has desirable numerical properties). Finally, the Faust form of the resonator is derived.
