Tektronix provides test and measurement instruments, solutions and services for the computer, semiconductor, military/aerospace, consumer electronics and education industries worldwide.
Satellite orbits 22,300 miles above earth’s equator where satellites circle earth at the same rate the earth rotates.
Industry:Software
The return of the electron beam from the right to the left side of the raster after the scanning of one line.
Industry:Software
A shadowy or weak image in the received picture, offset either to the left or right of the primary image, the result of transmission conditions which create secondary signals that are received earlier or later than the main or primary signal. A ghost displaced to the left of the primary image is designated as “leading” and one displaced to the right is designated as “following” (lagging). When the tonal variations of the ghost are the same as the primary image, it is designated as “positive” and when it is the reverse, it is designated as “negative.” See Multipath Distortion.
Industry:Software
The rate at which the screen’s scanning beam is swept from side to side. For (M) NTSC systems, this rate is 63.556 μs, or 15.734 kHz.
Industry:Software
ITU-R BT.1124 standard reference signal found on scan lines 19 and 282 of (M) NTSC systems and on line 318 (B, D, G, H, I) of PAL systems. This signal allows for the removal of ghosting from TVs by filtering the entire transmitted signal based on the condition of the transmitted GCR signal.
Industry:Software
A) The –40 IRE pulse occurring at the beginning of each line. This pulse signals the picture monitor beam to go back to the left side of the screen and trace another horizontal line of picture information.
b) The portion of the video signal that occurs between the end of one line of signal and the beginning of the next. A negative-going pulse from the blanking signal used to genlock (synchronize) equipment. It begins at the end of the front porch and ends at the beginning of the back porch.
Industry:Software
A supplementary point included on the tangent to the acquired point in order to force the line to begin and end on the acquired points.
Industry:Software
A weak, secondary, ghost-like duplicate video image in a video signal caused by the undesired mixing of the primary signal and a delayed version of the same signal.
Industry:Software
The mirage-like haze at the boundaries of picture objects, seen in DCT based compression algorithms at (too) high compression ratios. The effect is most noticeable around text and high-contrast geometrical shapes.
Industry:Software
A) Any system connected to the network. b) A device where module( s) can be connected, for example: an IRD, a VCR, a PC.
