Definition: Jitter is an error in a digital circuit caused by timing variations of the discrete samples that make up a digital signal. Jitter can be caused by several things, including inaccuracies in the digital clock, which is supposed to produce a timing pulse at specific intervals, by DC ripples in the power supply and by the data stream itself. Jitter is a digital phenomenon that can produce noise and degrade the sound of a digital audio system
