I've stayed out of this one so far, but I gotta agree with Dick. A tuned
circuit such as a PI-net is a resonant circuit. Resonance means that the
circuit stores energy. And without reosnance, as Dick so aptly put it,
you'd have no flywheel effect.
And yes the resonant frequency of a Pi-net is VERY dependent upon its
load impedance.
