| Jitter | Small, rapid variations in a waveform
due to mechanical disturbances or to changes in the characteristic of
components. They are caused by variations in supply voltages, imperfect
synchronizing signals, circuits, etc. | | JPEG, JPG | The JPEG (Joint Photographic Experts Group) image files are files in a
lossy format. The DOS filename extension is JPG, although other
operating systems may use JPEG. Nearly all digital cameras have the
option to save images in JPEG format, some at different compression
levels, such as fine and standard. The JPEG format supports full color
and produces relatively small file sizes. Fortunately, the compression
in most cases does not detract noticeably from the image. But JPEG files
do suffer generational degradation when repeatedly edited and saved.
Photographic images are best stored in a lossless non-JPEG format if
they will be re-edited in future, or if the presence of small artifacts
(blemishes), due to the nature of the JPEG compression algorithm, is
unacceptable. JPEG is also used as the image compression algorithm in
many Adobe PDF files. |
