Abstract :
A brief tutorial is given on what aliasing means. Plots of some relevant functions are shown. Some of the conventional wisdom about aliasing is described, and why that wisdom may not be so wise is explained. Aliasing is actually an image processing phenomenon involving the Fourier transform, convolution and the convolution theorem.<>
