"The fact that the frequency of the ringing is not an integer multiple of the frequency of the signal, by definition, makes it enharmonic."
There is no single frequency of this signal. It consists of a range of frequencies. Linear time invariant systems do not output frequencies that are not present in their input. They only change the amplitude and phase of the input frequencies.
I gave you bad advice when I suggested you read a book on Digital Signal Processing. You are not ready for this book. You should take a course on Signals and Systems. Perhaps the following link will be helpful, I haven't checked it out, but at least it is free.
