Aliasing due to unwanted, spurious out-of-band signals is a problem in many applications that use A/D converters. These signals, if not filtered properly, can seriously impact the performance of a ...

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 ...

Q: What is an anti-alias filter, and do I need one? A: At its simplest an anti-alias filter removes unwanted high-frequency signals from the signals you want to measure. Let's look at why you might ...

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 ...

This article is part of the Ideas for Design Series: Vol. 3, No. 9. Many communications and sensor applications require a bandpass filter with wide bandwidth. This filter typically requires precision ...

Does anyone know if there some way to apply shader-based antialiasing (FXAA, SMAA, MLAA, etc.) to video footage that is already rendered? I'm trying to clean up edges on footage from an old 3D game at ...

The relationship between a signal’s constituent frequencies and the sampling rate used to quantize them is fundamental. As shown in Figure 1, sampling a signal that has a given spectrum creates a ...
