Jitter period is the interval between two times of maximum effect (or minimum effect) of a signal characteristic that varies regularly with time.
Instantaneous packet delay variation is the difference between successive packets—here RFC 3393 does specify the selection criteria—and this is usually what is loosely termed "jitter", although jitter is also sometimes the term used for the variance of the packet delay. As an example, say packets are transmitted every 20 ms.
where u is the spatial frequency and is again the amplitude of the jitter (note that as the jitter approaches infinity, the value of the function tends towards zero). For spacecraft, operation in a vacuum often means low mechanical damping. Meanwhile, spacecraft are compact and rigid, to withstand high launch loads.
Bufferbloat is the undesirable latency that comes from a router or other network equipment buffering too many data packets.Bufferbloat can also cause packet delay variation (also known as jitter), as well as reduce the overall network throughput.
Jitter is the deviation in frequency of a signal. Jitter may also refer to: Jitter (optics), the oscillatory motion of the image with respect to the detector, which blurs the recorded image; Delay jitter, in packet switched networks; Fixation (visual) or retinal jitter, the maintaining of the visual gaze on a single location

The circuits used to control these frequencies do permit a very small amount of flutter (usually termed jitter), but the level is far below that which the human ear can discern. The linear sound track on VCR video recorders has much higher wow and flutter than the VHS-HiFi high fidelity track which is contained within the video signal.
