Tektronix provides test and measurement instruments, solutions and services for the computer, semiconductor, military/aerospace, consumer electronics and education industries worldwide.
The signal-to-periodic noise ratio is the ratio in decibels, of the nominal amplitude of the luminance signal (100 IRE units) to the peak-to-peak amplitude of the noise. Different performance objectives are sometimes specified for periodic noise (single frequency) between 1 kHz and the upper limit of the video frequency band and the power supply hum, including low-order harmonics.
Industry:Software
Sound which reaches a mike or listener after one or more reflections from surrounding surfaces.
Industry:Software
A) A measure of the sound pressure created by a sound, usually in the units of dB referred to 0.0002 microbar of pressure. b) A measure of acoustic wave force. The force that sound can exert against an object; our ear drums are an example. It is measured in dB and is “0” referenced to 1 dyne per square centimeter.
Industry:Software
A microphone type that picks up sound relatively evenly from all directions.
Industry:Software
Number assigned to an event or device that determines the order in which it will receive service if more than one request is made simultaneously.
Industry:Software
In PC video, a MooV file that contains all of its video and audio data, instead of including references to data in other files. See MooV.
Industry:Software
The range between the lowest and highest signal frequency of a given video signal. In general, the higher the video bandwidth, the better the quality of the picture. Video bandwidths used in studio work typically vary between 3 and 12 MHz. Consumer VCRs are generally capable of 3 to 5.5 MHz.
Industry:Software
Any interface (hardware) device connected to a computer that adds more functionality , such as a tape drive. Also, a mass storage or communications device connected to a computer. See also External Devices and Internal Drives.
Industry:Software
In video transmission, this may refer either to a signal or to the picture produced. a) Signal: Waves reflected from structures or other objects; waves which are the result of impedance or other irregularities in the transmission medium. b) Picture: “Echoes” observed in the picture produced by the reflected waves.
