Previous articles in Planet Analog make mention of the “aliasing effect.” Most EEs agree in the importance of the aliasing effect as a noise source and take for granted that anti-aliasing filters are ...

In part 1, we started to make some intuitive connections between near-Nyquist sampling, the addition of close-frequency sines, and how those signals would interact with perfect LP filters. Let's put ...

The old-fashioned method of antialiasing is called super sampling. An image that is 800x600 is upscaled by, for example, 4 times, to make an image that is 1600x1200 inside the graphics processor. Each ...

A research team at POSTECH has developed a novel multidimensional sampling theory to overcome the limitations of flat optics.

(1) Smoothing a distorted communications signal by applying techniques that add data or filter out unwanted noise. (2) Smoothing the jagged appearance of diagonal lines in a bitmapped image. The ...

Anti-aliasing smooths the raw and haggard edges on digital type and images on computer and handheld displays, wireless phones, printers, even digital cameras. Aliasing – jagged or stair-stepped edges ...

That's not necessarily true. Non-uniform sampling strategies still have problems with aliasing, although aliasing will look quite different then in the uniform case. Which is unfortunate. Non-uniform ...

This HEXUS.help guide explains multi- and super-sampling anti-aliasing. This HEXUS.help guide will assume you know the affects of applying a level of anti-aliasing (AA) on your 3D accelerator, be it ...
