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 ...

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 ...

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 ...

Our guest author is Matthew Hann, SAR ADC Product Line Manager, Texas Instruments. One of the most challenging aspects in optimizing the performance of a successive-approximation-register ...

ADI has introduced an alias-free ADC that aims to simplify front-end design and speed up time to market for precision DC-350kHz applications. Traditional precision data-acquisition signal chain design ...

Digital signal processors (DSPs) continue to receive a great deal of attention in new product design. For example, digital filter design reflects the importance of understanding and using this ...

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 ...

Analog Devices (ADI) has introduced the AD7134, an alias-free analogue-to-digital converter (ADC) that simplifies front-end design and speeds up time to market for precision DC-350kHz applications.
