In this feature on the nature of analog and digital signals, DSP consultant Nalin Pithwa starts with an excerpt from the cruise of the Revolution to introduce the concepts of analog-to-digital ...

In An Approximation to the Aliasing Effect, Part 1: The Origin I revisited some basic concepts about the aliasing effect, though I did it from a more visual than theoretical perspective. This second ...

A look at the Nyquist sampling theorem. How to deal with aliasing by attenuating signals using low-pass filters (i.e., an antialiasing filter, or AAF). AAF requirements for different ADCs. A deep dive ...

(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 ...

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

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 ...

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 ...
