(1) Small rapid variations in a variable (such as a waveform) due to deliberate or accidental electrical or mechanical disturbances or to changes in the supply voltages in the characteristics of components, etc. Jitter effects arising from the oscillating mirrors and other movable components aboard Landsat are often a cause of certain anomalies in the image Data received and must be compensated for by the Ground processing system. (2) Also called phase jitter, timing distortion, or inter-symbol interference. The slight movement of a Transmission signal in time or phase that can introduce errors and Loss of synchronization. The amount of jitter will increase with longer cables, Cables with higher attenuation, and signals at higher data rates.
