Jitter questions

    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?

    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.
