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 ...

Over the last few blogs we’ve been looking at DDCs and how frequencies are shifted and folded in the output spectrum. In the last blog, ADC Digital Downconverter: A Complex Decimation Example we ...

This idea details a design method for making anti-aliasing prefilter parameter tradeoffs between several factors. These factors include the filter pass-band magnitude accuracy, the filter order (the ...

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 ...

Previously on Digital Foundry we discussed how morphological anti-aliasing (MLAA) has evolved from a theory put together by Intel into a working technology for PlayStation 3, developed by Sony's ...

Primer on Nyquist and aliasing applied to the design of input filters for ADCs. Sampling a signal causes the original signal spectrum (blue) to create sum (purple) and difference (red) frequencies ...

A new Canon patent has emerged, and it involves a feature similar to Pentax. The concept behind said patent will function as the opposite of the sensor-shift multi-shot work--and the camera will make ...

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 early 2013, Nautel and Omnia introduced an AES3 composite multiplex implementation that uses only the left channel of a 192 kHz AES3 link. This implementation does not allow the entire 99 kHz ...
