Reference: Wikipedia explanation Reference information: Wikipédia Aliasing: In signal processing and related disciplines, aliasing is an effect that causes different signals to become indistinguishable (or "aliases" of one another) when sampled. en.wikipedia.org Repliement de spectre>/b>) : Le repli de spectre ("Aliasing" en anglais) est un phénomène qui introduit dans un signal qui module une fréquence porteuse ou dans un signal échantillonné des fréquences qui ne devraient pas s'y trouver, lorsque la fréquence porteuse ou la fréquence d'échantillonnage sont inférieures à deux fois la fréquence maximale contenue dans le signal. Note that although this talks specifically in the field of electronic sampling, the same principle obtains in statistical sampling too, although the reference to 'spectre' may no longer be relevant. I suspect the use of 'repli' / 'repliement' is all that is needed in this field in FR. This other reference, more related to statistics, may offer some understanding: Sampling and Aliasing Sampling www.cs.umd.edu › ~djacobs › CMSC427 › Aliasing Need smoothing before subsampling to avoid aliasing.
