If we want to take samples of some analog waveform, as in doing analog to digital conversions at some particular conversion rate, there is an absolute lower limit to the rate of doing conversions ...
Anti-aliasing smooths out jagged edges in games, but not all methods are created equal. Here's how it works, the differences ...
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 ...

(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 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 ...
If you’ve played a PC game in the past five years, you’ve probably stumbled across an anti-aliasing toggle while mucking about with your graphics settings. Switching it on can make everything on your ...
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 ...
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 ...
