To take the worst case scenerio & keep things simple :

          Re          Le
   0----/\/\/\/----)()()(---0
   |                        |
   |                        |
   +----/\/\/\/------| |----+
          Rz          Cz

Rz=Re
Cz=Le/Re^2

Zz = Rz + 1/(s*Cz)
Ze = Re + s*Le

Zeff = Zz*Ze/(Zz + Ze) = Re

Resonate Loop:

Zz + Ze == 0
we = Re/Le
damp factor = 1 (critical)

thus, there is no ringing.
