Tektronix provides test and measurement instruments, solutions and services for the computer, semiconductor, military/aerospace, consumer electronics and education industries worldwide.
Usually a block of 256 addresses. The lower eight bits of an address, therefore, specify the location within the page, while the upper eight bits specify the page.
Industry:Software
A scale factor coded in the bit stream and used by the decoding process to scale the dequantization.
Industry:Software
A signal that is a consequence of some forms of modulation.
When modulation forms two sidebands, one can sometimes be filtered out to increase efficiency without sacrificing information.
Industry:Software
An information service of 200-700 “pages” covering a wide range of topics including TV Schedules, News, Financial Market prices, Comment, Reviews, Concert and theatre information. Subtitles are typically transmitted on page 888 in the UK, on pages 199/299/399 in Belgium and Holland, on page 150 in Germany, and on page 777 in Italy. There are a number of variant character sets used, but the encoding is identical and all English alphabet characters plus numbers and most punctuation can be handled by any decoder. Includes support for eight colors, and limited block graphics, and selective revealing of underlying TV picture.
Transmitted on a variable number of lines (specified in header which contains basic information such as time, date, and channel), starting on line 12 and continuing for 7-8 lines typically. Found on broadcasts and some Laserdiscs; recording of TeleText signals is marginal on S-VHS, almost impossible on VHS, hence, the PAL/625 version of CC.
Industry:Software
A) A transform in the basic function that is not of fixed length but that grows longer as frequency is reduced.
b) A compression algorithm that samples the video image based on frequency to encode the information.
This creates a series of bands representing the data at various levels of visual detail. The image is restored by combining bands sampled at low, medium, and high frequencies.
Industry:Software
An outlet to which you attach cable connectors. Point at which the I/O devices are connected to the computer.

In rotational extrusion, the silhouette is rotated about an axis, like using a lathe to create a fancy table leg. The cross-section of an object created this way is circular. Such objects are often called “solids of revolution.”
Industry:Software
Using the ITU-R 601 4:2:2 digital coding standard, each picture occupies a large amount of storage space, especially when related to computer storage devices such as DRAM and disks. So much so that the numbers can become confusing unless a few benchmark statistics are remembered. Fortunately, the units of mega, giga, tera, and penta make it easy to express the very large numbers involved. The capacities can all be worked out directly from the 601 standard. Bear in mind that sync words and blanking can be regenerated and added at the output, only the active picture area need be stored.
Industry:Software
The frequency band (300 MHz to 3,000 MHz). In television, UHF refers to a subset of that band, the range from 470 MHz to 890 MHz, once allocated to TV channels 14 through 83.
Demands of other transmission services (such as police radios) have eaten into both the lower and the upper reaches of the UHF TV allocations.
Taboos eliminate still more channels. Nevertheless, the UHF TV band is seen by many ATV proponents as the most likely place to situate receiverincompatible and augmentation ATV channels.
Industry:Software
A partial or complete failure of interlace in which the scanning lines of alternate fields do not fall exactly between one another but tend to fall (in pairs) one on top of the other.
