Definition of aliasing in English:

aliasing

noun ˈeɪlɪəsɪŋˈālēəsiNG

mass noun

1Telecommunications Physics
The misidentification of a signal frequency, introducing distortion or error.
high-frequency sounds are prone to aliasing
Example sentencesExamples
- This type of signal distortion is called aliasing.
- Analog signals are usually low-pass filtered to remove most or all of the components above the Nyquist frequency in order to avoid aliasing.
- Any component of a sampled signal with a frequency above this limit is subject to aliasing.
- Optical signals were low-pass filtered at 500 Hz to prevent aliasing.
- Aliasing refers to an effect that causes different continuous signals to become indistinguishable (or aliases of one another) when sampled.
2Computing
The use of aliases to designate files, commands, addresses, or other items.
Example sentencesExamples
- Members of the system pay £3 a month for free reception and transmission of internet mail, mail forwarding and mail aliasing.
- As mentioned earlier, the host machine assumes multiple IP addresses using IP aliasing.
- Groff also allows for the aliasing of troff commands, macros and variables to provide alternative names for existing ones.
- It covers IP aliasing, packet filters, and ipchains.
- Although we had only four actual servers, we relied heavily on IP aliasing to create virtual personalities for each service.
3Computing
The distortion of a reproduced image so that curved or inclined lines appear inappropriately jagged, caused by the mapping of a number of points to the same pixel.
Example sentencesExamples
- Other than some aliasing on the car models and in the distant backgrounds, Rallisport features amazing graphics that certainly add to the game's play experience.
- As you can see, it looks pretty good, though aliasing is a bit more obvious.
- A rasterized image of the view from the light's position was rendered, and sampling errors occurred, including jagged edges and aliasing.
- The visual transfer is clear and colorful, but vertical lines still demonstrate some aliasing (they often look like stair steps).
- Standard-definition content looks good, but brings with it the usual artifacts: noise, line aliasing, and occasional interlacing.
- The movie does show a few problems from time to time, including some very bad aliasing and haloing, and some occasional moiré patterns, but for the most part the image is very clean and crisp.
- Otherwise, the graphics are smooth and free of annoying graphical glitches like glaring aliasing or slowdown.
- While you get solid, realistic colors with adequate detail, there is far too much grain, aliasing, and artifacting in the transfer.
- The only real complaint I have about the graphics is the game's aliasing and flicker.
- The worst spots are not that frequent, but the edge enhancement and aliasing are bad enough by themselves to spoil things.
