Tektronix provides test and measurement instruments, solutions and services for the computer, semiconductor, military/aerospace, consumer electronics and education industries worldwide.
This is one method of measuring a signal’s signal-to-noise ratio. It requires a waveform monitor such as the 1780R. Refer to the 1780R operator’s manual for a complete description of the signal-to-noise measurement technique.
Industry:Software
Camera feature that allows the operator to view the image as it is being recorded. Video viewfinders typically depict the recorded image in black-and-white.
Industry:Software
A microphone whose generating element is a crystal or ceramic element, which generates a voltage when bent or stressed by movement of the diaphragm.
Industry:Software
A unit of functionality provided by the host for use by a module.
A resource defines a set of objects exchanged between module and host by which the module uses the resource.
Industry:Software
Audible tape vibrations, primarily in the longitudinal mode, caused by frictional excitation at heads and guides.
Industry:Software
Term used for any machine using motors usually meaning a VTR, DTR, or video disk.
Industry:Software
Sampling data at a higher rate than normal to obtain more accurate results or to make it easier to sample.
Industry:Software
A tape with a magnetizable layer on which data can be stored.
Usually a workstation’s tape is packaged in a cartridge.
Industry:Software
Distance between image and a viewer’s eyes. In television, the distance is usually measured in picture heights. In film it is sometimes measured in picture widths. As a viewer gets closer to a television set from a long distance, the amount of detail perceptible on the screen continually increases until, at a certain point, it falls off rapidly. At that point, scanning line or triad visibility is interfering with the viewer’s ability to see all of the detail in the picture, sort of not being able to see the forest for the trees. The finer the triad or scanning structure, the closer to the screen this point can be (in picture heights). Therefore, high-definition screens allow either closer viewing for the same size screen or larger screens for the same physical viewing distance (not in picture heights).
When the effects of scanning lines and triads are reduced, other artefacts (such as temporal alias of panning called strobing) may become more obvious.
From far enough away, it is impossible to tell high-definition resolution from NTSC resolution.
