Tektronix provides test and measurement instruments, solutions and services for the computer, semiconductor, military/aerospace, consumer electronics and education industries worldwide.
The audio or video control equipment used for mixing sound and/or video. In video, a device for combining several video input signals.
Industry:Software
a) Technique for increasing picture repetition rate without increasing base bandwidth by dividing a frame into sequential fields. When first introduced, it also had the characteristic of making the scanning structure much less visible. NTSC uses 2:1 interlace (two fields per frame).
b) A process in which the picture is split into two fields by sending all the odd-numbered lines to field one and all the even-numbered lines to field two. This was necessary when there was not enough bandwidth to send a complete frame fast enough to create a non-flickering image.
Industry:Software
That part of a videotape recorder which converts electric variations into magnetic variations and vice versa.
Industry:Software
The lowest sampling frequency that can be used for analog-to-digital conversion of a signal without resulting in significant aliasing. Normally, this frequency is twice the rate of the highest frequency contained in the signal being sampled.
Industry:Software
Picture defects caused by interlace. These include twitter, line crawl, loss of resolution, and motion artifacts. In addition to causing artifacts, interlaced scanning reduces the self-sharpening effect of visible scanning lines and makes vertical image enhancement more difficult to perform.
Industry:Software
To magnetize by being put within the magnetic influence of a magnetic field.
Industry:Software
The maximum separation in time which can be given to regularly spaced instantaneous samples of a wave of bandwidth W for complete determination of the waveform of the signal. Numerically, it is equal to 1/2 W seconds.
