But you don't seem to be able to tell us what they do.

I think I've found my conceptual problem with my circuit. Tweaking the 
gain around the three-amplifier ring tweaks both amplitude and frequency 
- with more gain a lower frequency signal can still propagate around the 
ring.

I've got to find a mechanism that will separate amplitude from 
frequency. My copy of Williams and Taylor on electronic filter design 
may get perused again.
