Suppose you take a few measurements of a time-varying signal. Let’s say for concreteness that you have a microcontroller that reads some voltage 100 times per second. Collecting a bunch of data points ...

Anti-aliasing smooths out jagged edges in games, but not all methods are created equal. Here's how it works, the differences ...

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 ...

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 ...

If you've ever played a video game on your PC, you've probably seen a setting called "anti-aliasing", which smooths out jagged graphics. But there are different types of anti-aliasing, and some are ...

(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 ...

The 3D games we play and love are all made up of thousands, if not millions, of colored straight lines and other edges. And because of the way that these appear on your screen, they can often look ...

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 ...
