"Webthe dithering jitter is dictated by the low gain frequency step (∆f LOW = K LOWK V). In Section II we showed that the low frequency JTOL improvement afforded by the integral path is marginal. A more important function of the integral path is frequency pull-in range improvement [3]. Therefore, if an alternate means " - Dither jitter

WebAug 25, 2010 · For example, many consumer devices have jitter that exceeds +/‐ 2 nsec (+/‐ 2 billionths of a second). Such a device will have jitter‐induced distortion that measures only 78 dB below peak audio levels. These consumer‐grade devices produce jitter induced artifacts that are well above the threshold of hearing at most playback levels.

Jittering and dithering are both techniques of adding noise to reduce visible artefacts (such as banding) in an image. They solve different kinds of artefacts so they are used in different situations. Jittering moves sample positions in space to reduce artefacts caused by regular sampling.
