Tektronix provides test and measurement instruments, solutions and services for the computer, semiconductor, military/aerospace, consumer electronics and education industries worldwide.
In order to accurately send a signal through a transmission line, there must be an impedance at the end which matches the impedance of the source and the line itself. Amplitude errors and reflections will otherwise result. Video is a 75-ohm system, so a 75-ohm terminator must be put at the end of the signal path.
Industry:Software
A) The light from a nonselective diffuse reflector (in the original scene) that is lighted by the normal illumination of the scene.
That white with which the display device stimulates reference white of the original scene.
b) In production context, reference white is defined as the luminance of a white card having 90% reflectance and subjected to scene illumination. It is expected that there will be the capability of some discrimination of surface texture or detail within that portion of the transfer function incorporating reference white.
Industry:Software
The piece of hardware within the chassis that directs power from an electrical outlet to the chassis, the monitor, and other internal devices.
Industry:Software
In a digital video system, the number of pixels corresponding to the reference picture width. Some pixels at the borders of the picture region may be corrupted by the picture blanking transitions and by the effects of post-production image processing. Currently, SMPTE 260M defines a clean aperture within the production aperture, confining visible artefacts around the image to a thin border.
Industry:Software
A scheme for sampling at a frequency lower than that prescribed by the Nyquist sampling theorem.
Industry:Software
Transmission of data bits in groups along a collection of wires (called a bus). Analogous to the rows of a marching band passing a review point. A typical parallel bus may accommodate transmission of one 8-, 16-, or 32-bit byte or word at a time.
Industry:Software
Total number of distinct characters or numbers used in a numbering system. Same as Base.
Industry:Software
Consists of a regular patch mesh and is created with a single surface creation operation such as extrude, revolve, sweep, and smooth lofts.
Industry:Software
A switch that connects and disconnects a load resistance to a video input, used to terminate the line. In order for a video signal to be correctly transmitted without loss, proper end of line impedance is essential. Amplitude errors and reflections will otherwise result. A 50- or 75-ohm resistor is usually employed to accomplish this. When the termination switch is off, the unterminated video signal is looped to the next device where the signal can be transmitted in parallel. The final device in the chain must be terminated using the termination switch.
