Resonant rise?



Original poster: "Lau, Gary" <gary.lau-at-hp-dot-com> 

Hi Dan:

My understanding of the term "resonant rise" is that energy must be 
continuously applied at a system's resonant frequency, like giving someone 
on a swing a series of correctly timed small pushes, and this results in a 
growing amplitude of oscillations, until something breaks down or losses 
balance the input energy.  While this is what happens in a CW coil, I 
didn't think that it occurred in a disruptive coil.  There, it really 
starts with one big primary-push, and that energy is coupled to the 
secondary, with resonance being a necessary condition but not central to 
the voltage gain of the system.  Is my understanding or definition flawed?
