Determining the frequency of a transient

Trying to determine the frequency components of overshoot and ringing on a fast rise/fall transient.

If I have say a 10nS rise with some "hash" on the crest. Then expanding that portion of the wave can
I assume the various full cycle transitions are the actual frequency components in my circuit ?

The rise time is proportional to the time of the square wave and is made by amplifying the sinewave using high gain. So it's dependent on gain and the time of the sine wave. However, the time of the square wave is the biggest factor when comparing the rise time of let's say a 1KHz square wave to a 1MHz square wave. And I believe overshoot, undershoot, and ringing are caused by resonance.
