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 ...

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 ...

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 ...

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 ...

When using an active front-end amplifier to drive a high-speed converter, designing an anti-aliasing filter (AAF) can be a difficult task. It’s important to get it right because anti-aliasing is the ...
