Jitter: Definition & Understanding Scientists' Usage

[dervast]

Good morning:) I have noticed that many scientists use the term jittert slightly different than others :)
How can i denote the term jitter? Do u have sth in mind?

Okay, I'll bite. What is "jitter?"

I don't know what jitter is .. that's why i am asking

I know it from engineering (DVD mastering and such). There jitter is the deviation of an event´s scheduled arrival, in time or space. So maybe on a DVD the next pit should be read in 5 µs, but comes typically after 5 µs +- 100 ns. The ns are jitter.

Thx a lot for the answer.. So if jitter has to do with deviation perhaps a mathematical type exists

Then there's also zitterbewegung (or something like that) which translates roughly to "jittery motion". It comes up in relativistic quantum mechanics to describe a rapid oscillation.
