An abrasive tape used to clean and lap heads that are unevenly worn, stained, scratched, etc. Should be used with caution and should not be used on ferrite heads. This also applies to gray tape.
Industry:Software
A point of zero voltage potential. The point in reference to which all voltages are measured.
Industry:Software
Hum caused by currents circulating through the ground side of a piece of equipment due to grounding different components at points of different voltage potential.
Industry:Software
An electrical wall outlet that accepts a plug that has a grounding prong. In the USA, all properly wired three-prong outlets provide a ground connection.

A group is any arbitrary collection of polygons; a subset of the database, usually the group represents a coherent object. A group could contain all the polygons constituting the model of a chair, or it could contain twenty such chairs and a table. A polygon can only be in one group at a time, but it can move to another group.

The ITU-T Group 1 to 4 specify compression of black and white documents and the operation of facsimile equipment.
Group 3 (also known as G3 or T.4) is presently the most important standard in the world of fax and document storage applications. G3 compression features modified Huffman encoding. The ITU-T Group 4 (also known as G4 or T.6) is an improvement of ITU-T G3, dedicated to digital telephone lines, in particular ISDN.

a) A signal defect caused by different frequencies having differing propagation delays. b) This distortion is present when signal components of different frequencies experience different delays as they pass through a system. Distortions are expressed in units of time. The largest difference in delay between a reference low frequency and the other frequencies tested is typically quoted as the group delay distortion. Group delay problems can cause a lack of vertical line sharpness due to luminance pulse ringing, overshoot, or undershoot. The Multipulse or (Sin x)/x signals can be used to check for group delay in the same way as these signals are used to check for chrominance to luminance delays.

a) A GOP starts with an I-picture and ends with the last picture before the next I-picture. b) A picture sequence which can be coded as an entity. For instance, it is possible to cut between GOPs.
For that reason, the first picture in a GOP has to be intra-coded (I-picture).
Time codes are carried on GOP levels.
Industry:Software
Additional safety margin between two transmitting symbols in the COFDM standard. The guard interval ensures that reflections occurring in the single-frequency network are eliminated until the received symbol is processed.
Industry:Software
A modeling object visualized in the presence of another database which will serve as a visualization support but cannot be modified.
