Abstract :
This paper deals with the moire effects that are observed when we draw, on a computer screen, the family of all the concentric circles of integer radius less or equal to R with R efficiently large. The goal of this article is to give an explanation of the phenomenon using the fact that the circles that are drawn on a screen are not real ones but “discrete ones”
