While taking some probability, statistics and stochastic processes courses
about ten years ago, these confusions came up a lot due to term "chaos"
suddenly bursting out inappropriately from several media. To clear up this
confusion, the instructor explained the difference something like this: the
definition of random events, such as the toss of a fair coin (probability of
either event = 0.5) supposes that there is no information about the initial
conditions nor prior trials which will in anyway help to determine the
outcome of the succeeding trials. The term "chaos" refers to a particular
type of nonlinear partial differential equation (possibly recursive?) where
the input directly effects the output, but in a nonlinear way (I'm treading
deep water here).
Regarding the (patented?) VC Chaosccillator, I've read several references to
VCOs going chaotic by plugging the output into the FM input and varying the
amplitude. Hmmm....
On a completely different topic entirely without relation to chaos or VCOs
plugged into themselves, a really handy module might have a VCO and an
undedicated VCA in the same package. Think of all the things that would allow
one to patch up. I doubt there's a patent against having a VCO/VCA module.
