2. aliasing - Verb
aliasing
present participle of alias
aliasing (plural aliasings)
(signal processing, graphics, sound recording) Distortion caused by a low sampling rate, such as a moiré effect or jaggies.
Although aliasing in most systems is unwanted, it should also be noted that it can be exploited to provide simultaneous down-mixing of a band-limited high frequency signal (see undersampling and frequency mixer ). Source: Internet
Being forced to use a hybrid time domain (filter bank) /frequency domain (MDCT) model to fit in with Layer II simply wastes processing time and compromises quality by introducing aliasing artifacts. Source: Internet
Converting outlines requires filling them in; converting to bitmaps is not trivial, because bitmaps often don't have sufficient resolution to avoid "stairstepping" ("aliasing"), especially with smaller visible character sizes. Source: Internet
Decreasing N, causes overlap (adding) in the time-domain (analogous to aliasing ), which corresponds to decimation in the frequency domain. Source: Internet
Filter mosaics, interpolation, and aliasing The Bayer arrangement of color filters on the pixel array of an image sensor. Source: Internet
Furthermore, as any aliased signals are also typically out of band, aliasing can often be completely eliminated using very low cost filters. Source: Internet
