Tektronix provides test and measurement instruments, solutions and services for the computer, semiconductor, military/aerospace, consumer electronics and education industries worldwide.
A video signal in which each component remains within the limits specified for the video signal format; that is, it does not exceed the specified gamut for the current format.
Industry:Software
A feature that synchronises the modulator or modifier effect to the frame rate, thus preventing the effect from drifting or appearing incoherent.
Industry:Software
The decrease in level which occurs when a piece of equipment is inserted into a circuit so that the signal must flow through it.

The luminance range that can be displayed on a theatre projection screen is the ratio of maximum to minimum luminance achievable during projection of film. The maximum achievable highlight is determined by light-source output capacity, projection optical efficiency, the transmission of minimum film densities, screen gain, etc. The minimum is the luminance contribution from house illumination and other stray light, plus optical flare raising black levels, and the transmission of maximum film densities. Measured values in typical first-run theatres show luminance ranges of 500:1 to 300:1 (usually limited by house illumination).

Algorithm used by the UNIX compress command to reduce the size of files, e.g., for archival or transmission.
sequences (strings) in its input. It maintains a table mapping input strings to their associated output codes. The table initially contains mappings for all possible strings of length one. Input is taken one byte at a time to find the longest initial string present in the table. The code for that string is output and then the string is extended with one more input byte b. A new entry is added to the table mapping the extended string to the next unused code (obtained by incrementing a counter). The process repeats, starting from byte b. The number of bits in an output code, and hence the maximum number of entries in the table is usually fixed and once this limit is reached, no more entries are added.
The algorithm relies on repetition of byte
Industry:Software
A small device, not working by itself, designed to perform specialised tasks in association with a host, for example: a conditional access subsystem, an electronic programme guide application module, or to provide resources required by an application but not provided directly by the host.
Industry:Software
A clone of an object. If you modify the original, all the instance objects are likewise modified.
Industry:Software
The luminance range, recorded may be reduced from the luminance range, scene intentionally and/or by the limitations of the recording system. Most systems have a maximum effective signal level limiting the high end, and noise limiting the low end. All of the scene that is of interest must be placed within these two limits by the choice of an appropriate transfer function. Some analogue functions permit gradual transitions to overload and/or noise. Digital functions have inflexible limits imposed by the number of levels permitted by the bit assignments.
Industry:Software
A pickup pattern which is equally sensitive to sounds from all directions.
